Making it nest really isn’t too much problem, it’s how to represent it configuration-wise.
And yeah, that won’t ever come to 0.2.3, just to nightlies.
As far as speed, I think it’s related to playlists… I’m going to change the playlist stuff and see if I can’t speed it back up. It used to be pretty much on part with 0.2.3 on slow machines, and much faster than 0.2.3 on fast machines.
It’s a work in progress.
