Nice, but has problems Rated 4 out of 5 stars

Bad support for OPML files generated by other applications (FeedDemon, RSSOwl, Thunderbird) is bad. Or, rather, non-existant, since I had to correct the file with sed (Thunderbird's one, it was the closest).

No additional support for authenticated feeds, except for what live bookmarks provide. That is, the only option to store login and password is within the URL, and they behave badly with Livejournal secure feeds, again and again asking for credentials. But - lo and behold - you click on such feed, choose "Reload", and it loads all right. Sometimes not on the first try, though.

The interface is good, though, and I'd really like to be able to use it.

Support on the forums is slow...

This review is for a previous version of the add-on (1.1).
