Great new tools for stroke endings, thank you! When I force a stroke ending to align to x-axis, save the file and reopen it, the stroke ending is auto-aligning again (to x or to y, depending on the angle of the stroke).
Can you check what file format version is set in Font Info > Document? Setting it to “4” should fix it. I added an error message to avoid the “downgrade”.
Check! The setting to “4” did it. Thank you!
