A few bugs observed:
Outliner column settings rearranged by themselves, i.e. settings not saved. Ticks next to given items not always indicate their actual use/disabled status only after clicking, re-clicking.
Custom keyboard shortcut for “Enter composition mode” sometimes works, other times doesn’t.
Style box in format bar stretches length of half football field, pushing everything else (font, alignment etc.) to extreme right of window.
Under Options-Editing-Formatting-Main text style… , I cannot extend paragraph length further from “22 cm”, although it is quite possible I’m doing something very wrong.
