A feature I liked of facebook (before I stopped visiting) was where it would show "on this day 5 years ago" Is there a way I could set-up a skin to show this kind of functionality, and be able to select how many years back (one to twenty years).
I think this is a tricky ask, so no problem if not.
The biggest issue could be the reference source for your historical images or text content. Would that be from within your album or from multiple albums or a database? A single album with all of your historical information might be doable, a database would be beyond most skin authors, I think.
