Can I restore version 8 UI? I absolutely hate this version 9 UI - upgrades are supposed to make user experience better but this is far worse.  The editing of callouts is a huge downgrade in this version and the manipulation of the canvas is too.  The proportions of the playhead and the arrows and not being able to resize the track heights is irritating me to no end.
