[Feature Request] Filter by Artist/Album

[Mediaklan]

Hi all exaile dev-team ! First of all, thanks for your great app I'm currently using ! Great job guys !
As suggested in exaile forum, I'm posting here my feature request :
----------------------------------------------------------------------
Filter by artist and/or album for the current playlist
----------------------------------------------------------------------
I would like to use something similar to Banshee (I think this feature is implemented in Banshee, not sure about that) :
When selecting an album/song from an artist, I can filter all my collection to show only all his albums and easily add all these to the current playlist.
Thanks again !
