I was under the impression that you were going to add an "EDIT TAGS" option to the Play,Browse,Delete,... context-menu in the Result Tab,
because the way the existing Tag Editor works it is basically unusable / useless.
hmmmmmmm
I would be even happy, if you just turned the "artist","title","album",... labels in the file info pane at the results bottom into buttons (with same text).
That way when we click the given button the tag in question would swap places between the two files.
Lets face it ... most of the time we just want to steal the better tags, to go with the file we like more. (no editor would be needed at all then)
