I've completed the next part of integrating BrickLink's minifig data into Brickset. The Minifig Browser (linked to on the Browse tab) lets you see all minifigs in a particular theme and the sets they appear in. The sets in the list are coloured green if you own them (and you're logged in) making it a breeze to see which minifigs you own in the sets you own.
I'm not done yet with this, I'll add more features when I find the time (and can think of them!)
