Moved.

This should have gone to the MM wishlist. Could the admin please move it to there?

You can't, the media tree is duplicated across each tab. However, which nodes are expanded vs. which are collapsed is saved per tab. So you could, for example, have a "Playlist" tab with all the nodes collapsed except for the playlist node, a "Video" tab with all nodes except video collapsed, etc.

Hi, how can I make a specific Tab display only a specific node of the Media Tree, e.g. the Playlists node? And another Tab only the Video node, etc. How can this be done?

Every Tab displaying the whole Media Tree is useless!
