It'll be great if we could manage our favorites in separate folders, that'll be cool :)
Night_Wing, I think that this subject is about the posts themselves versus the favorites section of profiles.
....a better solution would be to adopted a feature from Konachan.com/.net where after having added to favorites the option wording will change to, "Remove from Favorites". This would eliminate any doubt in the users mind about whether or not the pic has been faved.
I have seen this toggle button' type thing done before. I think it can still cause a false sense of accomplishment if there's a deep rooted error, but I'll second the suggestion to our admin. I like the font background color change so I don't have to squint to see the words sometimes.
