Am liking this plugin more and more as I muck about with it :)
One suggestion: would be great if feeds could be deleted out of order. Imagine that I want to delete my first feed after adding 10 after it - currently I'd have to delete them all and start over!
While I'm here, another thing I'm wondering about is caching. For example, I changed the size on my thumbnails, and only new feeds pick it up. All older feeds still appear with the old size. Any tips on how to clear the cache quicker or at least punctually?
