Currently double-clicking on the podcast title will start playing the oldest episode from the feed (for some podcast this may mean episodes from 2008). This behavior afair was introduced some time ago after someones request.
The previous behavior was to play the most recent episode, which imo worked much better. Most of the time i'll have one new episode in a feed and to listen to it i now have to expand the podcast and select that episode instead of just double-clicking the podcast title like a normal human being.
So my wish is to change this behavior to:
Play the oldest new episode first (and by new i mean downloaded and not listened yet), otherwise play the most recent one.
