aescripts + aeplugins

I'm sure this has been asked somewhere before, so I apologize in advance, but is there some way I can favorite a script so that I can remember that I want to pick it up later, let's say, on payday? There's so many good ones out there, it's hard to keep track of them all. I've seen the add tags button/feature, but wasn't quite sure what it does. I'm thinking that may be the answer to my question though.
