First, I really like RSSBandit -- best aggregator I've found.
I tend to look at the list of items in a feed and (ctrl-) click those I want to follow, so that I end up with a few open tabs. Unless I am missing an option somewhere, I find I now have to go back to the feed tab each time. Could we have the option of opening new tabs 'silently', without them getting focus automatically.
The best way to get a feature request added to the list is to file a feature request at http://sourceforge.net/tracker/?group_id=96589
