Changelog

Settings screen further modified for really small iPads
Added backup files for when saving over an existing filename
Added a setting to turn that feature off if needed.
Added a confirmation message after saving, which checks that the saved file has been created correctly.
Added a Please wait message for large charts
60% reduction in the time taken to save large charts.
Now recognises tent stitches in OXS files saved by DP Software
Now corrects the backstitch locations in OXS files created by DP Software in Europe where the decimal character could appear as a comma instead of a point
Moved zoom slider back under the grid for better control
Added stitch count to bottom right of screen
Added total edit time to the bottom right of screen

Fix to Charts and PDF list placement - (these were not fully visible on some iPads with smaller screens, while in landscape mode.)

Changed the Files tab layout to visually separate import area from the PDF area.
Changed the way that triangle part stitches (which can be treated as 1/4 or 3/4 stitches) are rendered when in stitch view - these now show as triangles.
The thumbnail image while designing now shows the triangular stitches too - previously these weren't visible because the image size was smaller.
Similar changes to the color preview page in the exported PDF
Added a 1mm bead to the other sizes

Added a new way to do point-to-point backstitch.
If you set the new Settings value of 'BS = "join the dots" then instead of dragging lines out from 'here to there',
you just tap points one by one and backstitch will join the dots as you go.

Added the ability to use beads (2 to 6 mm), and recognise beads in a chart from MacStitch/WinStitch.
In order not to crowd the toolbar, French Knots and Beads all work from a single toolbar button.

Fixed an issue causing a crash when importing an image with very few colors.
Dithering (deliberate confetti) is now optional - a switch is on the file tab next to import.
Left panel has been made narrower so as to allow more design space
Zoom slider has been returned to the left panel under the navigator , so that it is not accidentally activated by the hands
Onion skin image on/off slider has been moved to above the chart area for the same reason.
'Highlight current color' now works in all modes, and will highlight using a CIRCLE in some modes, or by changing color to red in symbol modes
Highlight current color now highlights halfstitches too
Stitch Count was resetting to zero after undo.

New: Added chart title to top of design screen
New : Added a mini navigator to the portrait view , which works like the large one in landscape view, allowing you to quickly navigate around the design.
New : In portrait mode , dragging the mini palette to the right will reveal the larger palette, file selectors , and settings screens.
New: Added tent stitch drawing style to allow better compatibility with Mac/WinStitch files

Fix: PDF was not using symbol fonts for half stitches
Chg: Attempts to prevent saving when there is only a blank filename, or one that does not end with OXS
New: Preference setting to make the app keep the screen alive while it is open

Improved 'start point detection' for backstitch when using 'corners only' mode versus '9 points' mode.
If opening an OXS file which contains blends, the app will attempt to display a blended color, (although you cannot create a new blend in MobiStitch)
It will remember the blends contained in a file from elsewhere, and preserve them if the file is resaved
It will also accept and resave backstitch strands and colors, (although like blends, these are not supported in Mobistitch)
Now formats the thread numbers for a better sort order, so that 10, 100, 11 sort as 10,11,100
When opening a chart, if the screen is empty, you will not be asked to confirm the opening task.

Improved backstitch detection when erasing backstitch using cloth color
Eyedrop tool now tries to pick up backstitch color where present.
New slimmer palette rows to show more colors at once. (A preference lets you go back to the larger size if using fingers rather than a pencil)
New preference to enable/disable the addition of pink guidelines when tapping the rulers.
Fixed temporary backstitch color change happening on most recently added backstitch line.

Fixes messages about plugins
Fix for some people not able to import an image

Fix - It was possible to add 'invisible' stitches outside of the chart area.

Added a label for "current color" under the main grid.
Added extra thread manufacturer choices in the Settings screen, more than the original choices.

If you need DMC 01 to 35, reselect DMC in the Settings screen and a newer set of colors will be used as the default threads.
Slightly changed the scaling of onion skin images brought over from MacStitch or WinStitch.

Fixes 'failure to start' bug when Anchor threads were chosen as the default.
(If need be, delete the app and reinstall)

Adds 3 new symbol sets - you can now use symbols instead of simply letters
You can switch between the symbol sets on the Settings screen
These symbols work on screen and in exported PDFs, (and in Pattern Keeper)
The symbol selector area shows used symbols in blue, and the current symbol in red.
(If any symbols are used twice, the symbols will show up in red in the palette list.)
All backstitch is now governed by the 'snap to 9 points' preference setting.
As you begin to draw backstitch, the starting point shows as a small circle for confirmation of the start point

Some browsers add .XML to the end of filenames when downloaded, and it is not possible to stop that on an iPad, because it does not show the real extension by default in the Files app.
This build will now detect files that have downloaded with the extension .OXS.XML, as well as the correct .OXS

Build 199.26 changes the way that two finger pinching operates
It changes the way that an imported picture size is detected.
If an onionskin image is in use, it will display a grayscale version of it in the navigator in areas that have no stitches.

Fixes:
Backstitch of zero length can longer be created by accidental taps.
Charts containing zero length backstitches will have these stripped when they are opened.
The list of PDF files was the wrong height.
Some half stitches had symbols in the wrong position when exported to a PDF file

NEW: PDF output can now be single page or smaller sections
NEW: PDF key now includes stitch counts

Fixed a bug where flip left/right or flip up/down would fail if the grid had been scrolled

Fix for flipping a selection when backstitch exists (selection was becoming too large)

New: the ability to use an Onion Skin image which is embedded inside an OXS file coming from MacStitch or WinStitch.
Also amends the way vertical and horizontal simple backstitch lines are drawn.
Previously, these would appear at some point to the left or above the pen.
Now they snap to the closest vertical or horizontal line, (which may be below or to the right of the pointer)
Fixes bug with incorrect size when importing.
Imported image is kept at full resolution to assist tracing of gridded scanned charts (onion skin)
- was previously reduced to (chartsize * 4) pixels to save memory

Rearranged the files section because PDF export was being hidden after iOS16
Added the ability to draw quarter stitches.
Fixed an error that could occur if the maximum chart size was reached.
Added the ability to set both width and height of new blank charts. (Imported images take on the shape of the image)
Added the ability to remove long backstitches by clicking anywhere on the length while using cloth/erase color

Changed layout of files screen, as some users reported being unable to access the 'export to PDF' button.

Partial stitches now draw as triangles in 'stitched view' mode

Added 'Move' to the selection menu, so that you can select an area, and immediately start dragging it, rather than having to copy, erase, paste and move.
Other minor tweaks

Added the ability to use an image under the grid as underlay/onion skin, for tracing purposes.
You can now copy from one chart and paste into another while retaining the colors - colors will be added until the palette is full - after that, colors will be mapped to existing palette entries.
Added Coates Puppets threads definitions.
Added ability to change the 'default threads used for importing' on the settings page.
Added error checking around image use.. (very large pictures could crash the app if memory runs out.
Images are stored in a compressed form ,but when opened they use lots of memory)
Increased the number of colors allowable for importing an image, from 50 to 70
Because that could make a chart with more colors than you wish, we have also added
a new 'Remove least used color' option which allows for color reduction after import. (On Chart options menu item)

Fix: "remove white space' was removing too much of the chart.
