You mentioned Playing/Upcoming tracks. This does not enable the kind of operations I want.
This is the scenario I find myself in:
I have a lot of tracks in different folders of my own recordings which I'm now in the belated process of tagging and generally sorting out.
I have a Main Panel Layout and View that shows a long list of all these tracks. I go through this list tagging and making other edits often in outside applications. The context of these tracks I'm editing is often important; I like to see the other tracks around the current track. That is, the entire list.
While I'm doing this I find that a particular track I edited earlier is not correct or needs further changes. I search for this particular track using Search text or Advanced Search. (Manually scrolling through list or using Column Browser/Jumpbar is often not possible.)
I find the track but the context of that track, i.e. the long list of tracks, is gone. The search ends in a list of files matching only the search criteria.
Furthermore, when I'm finished with this particular track, I want to return to my last position in the long list of tracks. This is not possible without manually searching.
It would be nice to have a particular kind of search that does not show *only* tracks matching search results, but simply goes to the first match in the long list of tracks, similar to the way a simple text editor like Notepad does.
Or, after a search to be able to Go Back to last selected track among long list of files.
Also nice would be a way to Mark position in a list of files like in text editors like Vim. E.g. I have a particular track selected in a long list of tracks. I mark the position as e.g. 'a'. Search for another track. Then want to go back to the marked track by going to mark 'a'. Marks 'a-z' might be possible.
I realise MBee is a forbiddingly complex piece of a software already. I've been using MBee for several years and still I forget how to do something and it takes ages to find out how to do what I want. I'm not sure MBee should get any more complex

I guess I was hoping in original post that this was something possible.
