Cannot Resize Inspector / Visibility Area

Just using the visibility inspectors and linking, I already found some bugs. I tried the trick, linking MixConsole and Project, but it is quite erratic for me. I hide tracks in the mixer, and tracks disappear as expected from Mixer and Project. I hide other tracks, and tracks disappear from Mixer, but stay visible in Project. Also, disabled tracks don’t show up in the mixer’s visibility tab, so I cannot hide them there. It’s so buggy I un-synced the views again and leave it be.
