I have no way of knowing what "state" MC was previously in when I switch to it and the first thing I do is search.
Your needs are demanding.
Dunno. I do search Playing Now, often when doing DJing and stuff. I don't even know if my suggestion would drive me crazy, actually, because I
often lock two Playing Now splits, and then sometimes search one of them.
Split 1: Media Views and stuff
Split 2 (locked): My Headphone "upcoming and testing out" zone.
Split 3 (locked): The audience zone
I'm kind of surprised I hadn't noticed this peculiar behavior of Control-F before (unless it is a new thing, of course), because I do this sometimes, and it would have driven me crazy. Of course, when I'm doing this, I'm usually using an Audio view on the unlocked pane, and so maybe I wouldn't have noticed (or used the trackpad to select the search bar, which is equally likely).
So... Meh.
* I do search Playing Now sometimes on purpose.
* It is essential to me that Search searches the current view, in most cases.
* I'm okay with it if it is a little more difficult to search Playing Now when in a locked split view, if that makes people happy.
* I'm not okay with it (without it being optional) if it is
impossible to search Playing Now in a locked split view.
* I'm okay with it being optional, but it seems like a pretty niche request (considering that it violates the general rule that search searches the current view). But, whatever, I can kind of see it.
