The last days I played with my foobar-configuration and accidentily found a setting which allows to open the album list (or perform other actions) by just double-clicking on an empty space of a playlist.
Then I reinstalled foobar (to get foo_scroll) and now I can't refind the point in preferences where I can set the action.
Can someone here tell me where I can find this option?

Display > Columns UI > Playlist view ?

Thanks a lot. I just should have used the latest Columns UI version to find it... I didn't even think that the "special installer" of foobar wouldn't include it - which is now obvious to me...
