I wish there was a way to mark some of MY photos lying across/in different Google+ albums as my favourites!
Or say, in Picasa Web Albums, I want to find a way to mark some photos (which may be present in different albums of mine), and then later move/copy all those marked photos in one album.
I already know a work around to create spare email address and then tag all those photos with that tag. This work around is not very practical. Moreover, I won't be able to view all those tagged photos together at one place with one command, will I?
