I used MC for different type of parties (backgroundmusic, dancing music, party music), but I most the time act as the "One and only DJ"
So there was no need to have some kind of special setup for me.
If I will use MC for partys in a way you do, I'll be happy that you told us/me, how you use MC.
One of the biggest problems for users not familiar with MC (I think) is using the organisation tree especially when split view is active. Users often don't realize what they are changing (left pane/right pane of split view) when browsing with the organisation tree. So it's a good idea to close the organisation tree
and use the split view. I never even thougt of that!
Up to now I always had "Edit playing now in Action Window" active if anyone else handels MC. And no split view. So everyone could easyly browse through my playlists and Playing Now is always visible. But this doesn't bring good results: often they don't realize that this small windows shows the current playlist. They also never know, where to drop or dobble click to make a file instantly or later.
One of the biggest showstoppers for MC as a real party jukebox I think is that it doesn't allow to look a view (see discussion
here). If this feature would be implemented, it would be easy to allow party users to browse through playlists without changing eg. one split part which is fixed to playing now. Then you could leave the organisation tree open.
But your configuration is a realy good (and easy) workaround. Thanks for that.
