[Rhythmbox-devel] Create playlist from library selection

[Ed Mack <lists edmack com>]

Hi,

I'm quite fond of creating elaborate artist/album/filter combinations,
but when other people play different music I lose those selections, and
have to fuss around for another 5 minutes to get it as I please.

To sort this, I've created a menu item which makes a new automatic
playlist from the selection. This makes it a snap to create automatic
playlists (I always found the dialogue awkward, this WYSIWYG approach
works better) and flipping through favourite combinations is also very
easy too.

The menu item string is probably not the best, but I am of course here
for criticism ;).

Thanks
Ed Mack
