i dont like the way it handles opml files b/c when i add one and subscribe to podcast from it clears directory so i have to type in opml file again to subscribe to another.
apart from that its a great application
if you don't understand what i mean add the below opml and try subscribe to multiple podcasts from it without having to type in opml multiple times.
