So I was playing around with closing the tree pane and seeing how it would be to use the program like that. I hovered over a thumbnail and clicked "Tag". Nothing happened.
I know why nothing happened. But would a new user? I'm just a little suprised that clicking Tag didn't either open up the tree pane and the Tag AW, or that MC doesn't hide the Tag option underneath a thumbnail when the tree pane is closed. Personally, I think the former is the right way to go.
And I know this is probably analagous to the whole mute issue that's been debated and apparently dropped. But before Jim or Matt points out my apparent hypocrisy, I do see a difference between what I'm suggesting above and the current behavior of MC unmuting the audio.
First and foremost, this automatic action from MC only affects MC. It isn't opening a closed pane for another application. Secondly, by clicking the Tag option, I'm explicitly telling MC I want to open the Tag AW. MC can't do that without opening the pane back up.
