Right click menu on the dashboard
Right click isn't used very much in Millumin and would save a lot of boring setup on the dashboard. Right clicking on a clip on the dashboard should let you set its loop setting, edit (open the timeline if it is one), even colorising a single clip for better visibility (as you can with column headers), reveal in library, copy, paste.... the usual stuff.
I recently programmed a show that need 1/2 follow ons and the others all different play types. It took quite a while to to do 140 settings that would be easy with a right click.
Also in timelines, right clicking a keyframe in a timeline could allow you to change the easing.
