Does anyone know of a module or some other way to allow users to customize blocks or panes (or even regions) in a panel on their profile page (i.e.: the authenticated user could change the color background of the block, or add a picture to the background, could change the color of the borders and font, etc?)
That means the same blocks could be themed differently by all users.
Ideally each block / pane would have a tab with some kind of a drop-down allowing the user to select options to add HTML and CSS on a per block basis.
The site uses Bartik (D7.)
Any feedback on this would be greatly appreciated. :)
