"Delete Track" improvements

My workflow is that I create an "Uncategorized" playlist and import new music into there first. I go through the tracks in that playlist later and categorize the music into other playlists by genre or mood. Often I encounter a track that I don't want in any playlists - I want to remove it from my collection entirely and move the file to the trash or just delete the file. Right now I have to:

- Scroll to "All Tracks" and click it, and lose my place in the "Uncategorized" playlist

- Type in the name of the track to search for it

- "Show In Finder" and move the file to trash

- "Delete Track" in Mixo

- Scroll to click "Uncategorized" playlist again

- Find my place again.

It would be nice if I could just delete tracks from the entire collection, from within a playlist. Even better would be to be able to have the files in the filesystem moved to trash (or deleted) at the same time.
