- Lock pan and volume sliders in Track Control Panel: I repeatedly bump pan or volume in my efforts to move tracks around and I usually can't figure out what is wrong for a while. Unless there is already a way to lock them, I think that would be a useful feature. See this Forum post for details. Plus 2 votes.
- Disable Gain and Pan sliders: A way to delete or disable these controls in the preferences. There has been several times when working with several audio files at once these controls get bumped, so my gain is bad or my balance is out. I will backtrack tying to figure out how I "screwed this up" usually think the filter I applied didn't work right or something. I normally NEVER use them when editing. Typically I minimize the tracks I'm not working on to maximize the workspace which will hide a tweaked gain or balance control. (Plus 1 vote)
