Yearly statistic for watched movies

Hi,

I really love the statistic for Top watched Actors and Directors, but I would like same statistic for the move year.

Example how many moves i have seen from 1997, 2001 .. currently the only way to to this is to manually tag all watched movies with release year and then in my tags I can see this statistic, but to tag all movies is not that easy I know I tried :))

Thanks and keep up with the good work
Cheers
