Add auto-delete to podcasts.

As in, "Keep only the (select number) most recent episodes." It's very tedious to go through all the episodes and manually delete everything but the most recent 3. I have to use internet explorer(!) feeds for this, but then syncing to my walkman mp3 player doesn't work anymore.

I know there is something in the Winamp 5 Wishlist for this already. But it seems a pretty standard option in a lot of podcasting catching software. Maybe a vote on it can move it up the list of wishes?
