To see how many times you've done each workout video...

I got another idea for the site again...

I thought it could be interesting to know how many times you've done each workout video. To sort of have your own statistics. An idea is that you could have a small button under the videos that you can just click on once you've completed the workout. Then you could sort the videos after how many times you've completed them, just like you can sort them after length etc.

What do you guys think about this?
