Thanks, I think that's great.
May I make another suggestion?
I like to display my playlists with specific headings which is, of course, easy to do (using a customized headings set) but unfortunately, MC resets the headings to the default when I switch to the next playlist. Consequently, I have to redo the headings for each playlist I look at. The settings for displays needs to be persistent and if you set columns to "autosize", this setting should be persistent as well.
