Just noticed another minor display (or maybe doc) issue: if I set the hidden pref show_editor_scrollbars=false, contrary to the docs, the scrollbars never appear -- even when the document is longer than what the view can display. I can still scroll down via the scroll wheel though.
Interesting sidenote, Geany's horizontal scrollbar at the bottom is a bit odd in the way that it lets you scroll way out to the right even if you don't have any long lines. It tends to make me think I've got a really long line somewhere in my doc. One way I've seen this feature work in other editors is, the size of the scrollbar slider grippy thingy at the bottom varies depending on the max line length *of only the lines currently visible in the view*. More commonly though, the size of the slider thingy just gets set based on the length of the longest line in the whole doc, and that works very well.
