There's no way for me to edit an already-existing feed. If I tap-and-hold and then choose 'Podcast settings', I get information on the feed but I can't edit any of the details for the feed such as the feed's URL. I also can't get a standard system keyboard to pop up after highlighting text so that I can copy/paste text from the details listed like I used to be able to do.
There's no 'Advanced' option in the preferences menu. I rather liked that I could go in and tweak things without breaking out an xterm window and fiddling with the gpodder.conf file manually.
If I select a bunch of podcasts from a feed, then select 'Play', it reports 'Opening x episodes' (x being the number I highlighted), the episodes are marked as played but a player never launches to play those episodes.
