Could use a few extra improvements to make using it a smoother process.

• 1) The horizontal scrolling (linear or circular) is quite slow, a significant speedup of scrolling would be appreciated.
  • the zoom has a nice amount of control, so something similar would be nice for horizontal scroll.
  • i.e. if I scroll slow it moves slow, if I scroll fast it moves fast.
• 2) Scroll/Zoom to selection button (in the tool bar)
  • While the the zoom to selection is useful there are times where it is preferred to use a button click
  • When clicked it should zoom/centre to encompass the entire selection (instead of continuing to zoom further)
• 3) Zoom to selection doesn't work in linear mode. Maybe it should to be consistent.
• 4) Zoom to curser option, e.g. I'm holding command+scroll to zoom to where my curser is, instead of selection.

Proposal

Implement the above :)
