Filtering my content even better!

Am only new to Feedly, but have used Google reader for good now. favorites is a nice feature: it helps prioritise my reading by subscription and that's great. however, what i wish to see also is an old-facebook-style button next to each snippet saying "more of this feed" and "less of this feed". so, that i can prioritise my read on the go! wouldn't that be great? other than that, i love feedly: always wanted something like this for my browser, as google reader's own interface, albeit comfortable enough for recording and keyword-searching stuff i like, can be a bit bulky as a digest (and goofy, too).

Actually, one more complaint (just a tiny one though :P ). i can't seem to be able to UNshare items in Feedly once i share them here: have to go to GR to do that.

Also, with regard to Google Reader itself: it still has no way of renaming a tag (only folders can be renamed -- and this in a cumbersome way, too. BTW, the lack of clear distinction between a Tag and a Folder is truly mystifying in GR.) Anyway, would it be possible to mass-edit (incl. renaming) Tags from Feedly?

Many Thanks!
