Bulk editing of feed lists (think gmail checkbox + actions menu) would
be REALLY appreciated.
Well, according to the Google Reader blog, my wish has been granted:
There's now a link in the top right that says "Settings". Clicking on that link opens up a new screen that lists all of your subscriptions and labels, and allows you to make edits to more than one item at a time. We've also added a bunch of new filtering and selection controls. And there's a new feature as well: you can rename any of your subscriptions.
So a hearty "rock on!" to Chris Wetherell and the other Google Reader people.
