PicLens is neat. It even sort of works with FriendFeed. I just wish it would allow me to favorite Flickr photos from within PicLens. It's a pain to exit in order to favorite a photo and then find your way back to where you were. - Michael Hocter

I love piclens. My only annoyance is if I use it to browse photos, and find more than one that I like, once I tell it to open one of the pictures, it exits and I have to re-start the search in order to get back to the other pictures. - Phil Glockner
