I have not been able to tell if V. 9 added this, but the lack of user control of the windows impacts my use of SCS. We use SCS as a realtime sound effects system for podcasting and sound selection is on the fly. As such having a map of sound hotkeys in a tiny, scrolling window on the side is far from meeting our need. Instead a map of onscreen buttons which match keyboard hotkeys would be the way to go. Either combine this functionality with the sound list when not in edit mode or replace the list and eliminate the small hotkey map window.
The fact is, the SCS user interface is so quirky that we are constantly searching for an SCS replacement!
