Hi Matthew,
Wow you've been busy, well done. Seems to work for me.
#0002 Enable Scintilla's default popup editor menu on the split window editor so that there's a way to copy/paste/undo/redo/etc.
Does this mean that editing now fully works between the two split windows?
Closes bug #2983145[2] although the keybindings and main menu items still don't work in the split window.
Except for these of course.
#0003 Remove the widget reparenting in an attempt to make the plugin work on Windows again. Although I can't test on Windows, I think there's a good chance this will fix the issues and it seems to work fine on Linux as well. I base this on an old GTK+ FAQ entry[3]. If someone can confirm, it will close bug #2725342[4] and the plugin can be re-enabled on the Windows build.
#0004 Fix confusing terminology in Split View menu, which has annoyed me for some time. Closes bug #3203384[5] and feature request #2796316[6]
Agree, originally the menu matched the underlying GPane but GPane describes the *children* being *arranged* horizontal or vertical, whereas the menu was describing the *parent* window being *split* horizontally or vertically, the opposite thing.
#0005 Stop unsplitting on document close unless there are no documents left open. This patch just uses the first available document in the documents array instead of unsplitting when the document in the split window is closed. I left a TODO comment in there, I'll fix it later unless someone else has the time.
[..]
Bug #2984797[10] - this one has bit me numerous times. I honestly don't know if I fixed with my patches or if someone else fixed it in a recent revision, but it seem to no longer be reproducible for me.
Can't reproduce on 0.20 Release version either.
Cheers Lex
