Betá 4 is looking good. Looking forward to the next version.
Anyways, i don't know if this is plannend, but i would like to see a "rss://" and "rss:" intrigation.
so if i find a site that has a RSS feed, and links to feed like this: "rss://www.somelinkhere.com/feed.xml" it would add the feed to Feedreader.
Keep up the good work!
