Group by user agents

It is nice to see all user agents, divided by version.

But, how about a page where major players would be grouped, like Firefox, IE, Opera, Safari, Chrome and Android, Symbian, and / or some other relevant grouping?

Usually it is not relevant if it is IE 5 or IE 5.01. Also some fake their identity and it would be nice to have them both grouped and at sublevel listed like

Firefox            37%
  - Firefox 3.6 11%
  - Firefox 3.5  7%
  - Firefox 3    7%
IE                 35%
  - IE 8         5%
  - IE 7         3%
  - IE 6        25%
  - IE 5         1%
  - Other IE     1%
Opera              15%
