When adding songs to the current playing list, there used to be a function to REMOVE an artists songs from the current playing list - ie a X button that removed all the songs in the current playing list by that artist (now there is only a Favourites, Play, Add to playing, and an M for more that does little). This was/is an important feature when building long playlists. This seems to have disappeared in the last few builds - PLEASE can we have it back.
