This is bad. I currently have a category that has close to 40 feeds in it. For some unknown reason I when selecting the feed category the reader pane isn't showing the contents of the feeds.
When I tried to move a feed to a different category I noticed I can't drag and drop any more. This seems like a bad regression to me. The only way I can move a feed now is to edit the properties of it. This is way too labour intensive.
