I've been working with Feeds a lot lately. Pretty much in every project I am involved with. I am starting to consider it as an essential piece of Drupal infrastructure whenever external data of any nature is required to be pulled in.
During development and testing, one of the recurring tasks is to clear a bunch of feeds, and then re-import them. Instead of doing these operations on each feed, I thought it would be handy to use good old Views Bulk Operations to clear and import feeds in bulk.
