I used to enjoy this feature of DA wherein I would hover the mouse over the image and the date of upload would pop up. This was very useful in knowing how old/new the work is, if the creator has been active recently.
DA has removed this feature since a while. I would love to have this back.
Edit: I mean the pop happens when browsing galleries. Not when the image is opened by itself. So, if you browse the thumbnails on the homepage, you could hover your mouse on the thumbnails and the date of upload would pop up.
