(BTW, unti someone tell sme not to, I'm continuing to put feature requests in here...let me know if there's a better place)
This seems like a tiny code change that would make a difference in usability in PRV. I am a huge fan of the new track list features, it's just awesome, what with the filtering and saving filter sets, etc. One admittedly TINY but ever-annoying feature is this: I'm in PRV, looking at three tracks: 1, 2 and 3. Track 1 is currently the active track. I decide I don't want to see track 3 at all, so I ctrl-click on the little pen edit button next to Track 3 to de-select it. However, not only is Track 3 now not hidden, it has become the ACTIVE track by virtue of my having de-selected it! So I need to then go back and re-click on Track 1 to make it active again and truly hide Track 3. In this example, with only 3 tracks, not such a big deal. I'm often working with over 30 tracks at a time though, which makes it more annoying.
De-selecting a track from PRV to hide it should NOT change the active track. Simple as that.
