Can't adjust the volume on a clip. I add Volume (keyframable), and in its properties I click the + and I get my marking. I adjust the volume for that and it shows on the clip as well. But when I listen the volume hasn't changed. I save, quit, and re-open my project and the marking is gone. I try to do it again but this time it won't stick.

But that isn't the only one. When I add the Volume (keyframable) and try to add the adjustments by double-clicking on the clip itself, I get the mark, and I can drag it, but it won't stay at that level. If I drag it below the clip it vanishes all together. Not sure if that is intentional, but I would expect it to stay at the bottom and call it "mute".

Also, would it be possible to also have a "percentage" meter? I just don't know what 5% of 0dB would be... -55?
