The automation buttons in a Playlist toolbar all have a darker background colour than (for example) the colour of the Total Playlist Time ‘button.’
This got me thinking about two improvements:
1: The Event Time ‘button’ should have the same ‘button’ background colour as (for example) the NEXT button. This is a visual cue that it is clickable (it opens the Event Scheduler).
2: The non-clickable ‘buttons’ in a Playlist toolbar—the number of items, total time, and any others I have forgotten :)—should go back to the original ‘square corner’ look, as well as having a different colour as they do as present. This may sound very ‘nit picking,’ but it is again a very helpful visual cue to the user (you can click the rounded ones but not the square ones), and also very easy for Torben to do. 
Trust me: I’ve read a LOT of stuff about GUI theory, and a consistent GUI is a Better GUI!
