Hey. the idea just came to me;
Is it possible to mark a thread (say a tutorial by someone) as ones favourite?

If not, it'd be a great feature to be able to tag different threads as your own personal favourites.
It could also be a good way to keep track of certain threads if, say, a tutorial is posted in the thread in several steps and it has not been compiled into a pdf format or something similar.

I may just be nitpicking with this, but still...
What do ya'll think?
