Multiple Playlists

I realize this is a big feature considering all the management around it, but I am going to ask for it anyway.

I'd like the ability to have multiple playlists or "channels" that are a set of feeds grouped together.

Basis: I like listening to tech podcasts and do so everyday on the way to and from work. My wife does not. I'd like to have a set of podcasts (a channel) that I can switch to of items she does enjoy ("Wait wait, don't tell me", TAL, Radio Lab, etc.) Sometimes I might be in the mood for comedy and if I could have a comedy channel, that would be awesome. I really view DC as an alternative to radio and have come to see it as programming my own radio station.

Features:

• Individual feeds could be in multiple play lists (and potentially in a different order on each one). Individual items in the list would maintain new/listened state regardless of which play list they were played on. (If you listed to a particular show on one channel, you wouldn't need to listen to it again (or skip it) on another channel.)
• A channel management screen would need to be available and the play list sorting and categorization would need to be overhauled. It should be easy to add or remove feeds from individual play lists. And easier to sort the feeds. (Long Press, Move, Move Up is too many clicks to move a feed one (or 5) position)
• Play mode would let you easily switch to a different channel.
