Many times I've come upon the want to Fave a challenge. Just as we fave images. Some challenges have such a plethora of fun images to browse that I'd like to tag/favorite it. The recent Visual Puns challenges comes to mind. Not every image is a fave but as a group, they definitely are.
Excellent idea. Sometimes you just want to go back and look - with ease - at a cluster of pictures that appealed. Even though there are challenge archives, you can't always remember when they were, or what they were called.
