I've just upgraded to RSS Bandit 1.3.0.38 and I'm really pleased with it. This version successfully imported Robert Scoble's huge OPML file, has a refreshed UI, and seems to load large numbers of posts much faster (maybe due to disabling XSLT formatting).
IE7 introduces the ability to subscribe to any link in your default RSS aggregator. This function allows users to right-click a link and select the "Subscribe in default RSS reader" option. While useful for valid RSS feeds, this feature does not work for other content types. Whether this is specific to Internet Explorer 7, enabled by default, or a result of extensions like RSS Bandit is uncertain.
