-Zoom to object: when you select an object, the zoom in should be center in that position.
-Solo layer button(aside the lock buttons):when you click this, all the remaining layers automatically locks(yes you can lock each layer individually but when you have a lot of layers this can be helpful)
-Purge project:(like the most of audio daws like cubase)delete all the objects that are not in use in any event and layout.I can easily lost the track of the unused files if i don't delete them right away.In the end of a project it would be great to clean those unnecessary files to do the final export.
-Snap to edges option:it would make the level designing so much better.
Sorry if any of these are already available and i missed them out for some reason.
