After a recent import and feed-adding-spree, I've ended up with a lot of duplicate feeds. Most of them are due to the websites changing their feed URL, and some seem to have the same feed URL.

It would be great if TOR could find feeds with the same posts and provide a list so the duplicates can be easily reviewed and removed.

Possibly also show feeds which are a subset of other feeds, so you can remove the subset feed if it's covered by a full feed already.

Let me know if you need more information :-)
