I am making a comment just so I will see the project later. Swamped at work but in a week when I have some free time... I feel like a kid waiting on Christmas with presents under the tree.
There is a "favorites" button right under the submission title, which you can then access through "favorite submissions" in your profile.
Awesome, thanks for the tip.
A button I love, but for some irritating reason (I suppose because the lack of JS) takes you to the main favorites page every time you mark a post as favorite
