Installed GM just for this script - nice one, very useful!

I've been waiting for somebody to write this for a long time!

Thanks a lot

One minor thing though:
The description says "Tells you how many times your styles were installed - in total and separate", what does "separate" mean here? I only see the total install count on a user page, is there something else I've missed?

EDIT: see my answer below
EDIT2: Well, now that you've modified your script, it shows the same things as mine ( http://userscripts.org/scripts/show/50875 ). I guess we've been mutually inspired by our work.. ;)
