Thanks Sumalc! I'm just now getting to my computer for a code-session.
The project markers are actually
supposed to scale with the window, what's bothering me about your GIF is that the audio 'item' isn't! It should (see GIF below)!
The only issue I've encountered similar to this is that for some reason certain tracks that have been 'rendered' or 'frozen' do not scale with the window! Take for instance the GIF below... All of the audio tracks scale with the window except the first audio track, which is a frozen MIDI track.
[Edit]
Just added v0.64 to OP. Should have fixed the issue with track-name positioning and region/project marker display. Also, changed region/project markers to display at top of window instead of bottom, per request.
Now I'm working on other bugs.
