[Edit: It has come to my attention that the app only works if you have the latest Java installed, and probably only on a Mac as well. ]
I couldn't just leave it with a sloppy UI like that so read up on Java Swing Layouts a bit and made some minimal adustments.
Fixed in this version:
- Better resizing behaviour
- Better layout of control panel
- Better scrollbar behaviour
- TrackBuilder does not follow the end-point of the track to keep it "in view". This means you'll need to scroll manually.
