Favorite Threads button

Hi

Since this days i am reading some old threads from 3, 4 or even 7 years ago with really good info there, i thought it would be a good idea to have a "Favorite" button that saves thoose threads for your own query (and even from oblivion, being possible to resurrect them) whenever you want.

It can also be handy to keep track of thematic threads* that once in a while run out of activity, or thoose threads where you want to participate but you dont have time at the moment (so you save them to participate in the future)

*About the thematic threads, the locked post at the top of Free discussion section does its function having a list of all known, but i might not be interested in 99% of them... if i have the 1% in favorites i dont have to scroll all the way on the list, to find the ones i like and i want to participate.
