[Done] Group browsers in Dashboard (Vistor browsers)

It would be great if browsers could be grouped.

At the moment I get:
[ul]
[li] Firefox 10.0: 29%
[/li][li] Chrome 17: 29 %
[/li][li] Firefox 11.0: 8%
[/li][li] Internet Explorer 9.0: 4%
[/li][li] Internet Explorer 8.0: 4%
[/li][li] …
[/li][/ul]
This can be compared to Stat Counter -this page.

I would like to get
[ul]
[li] Firefox: 37 %
[/li][li] Chrome: 29 %
[/li][li] Internet Explorer: 8 %
[/li][li] …
[/li][/ul]
The view I would like to get can be compared to Stat Counter -that page.

Another idea to group browsers would be:

  • mobile devices
  • desktops
    – modern browsers
    – old browsers (IE < 8, old Moz, webkit etc)
