Group sites using folders or tags

For those with lots of sites, it would be useful to be able to group sites according to the client or project by using tags or folders.

Right now the best way to do this is to use site pinning which allows you to list some sites at the top of the list.

will be nice to group sites at least by root domain name

This would also be useful for site permissions

+1, slowly I got too many sites to manage. Having a group or sections or folders for the dashboard would be nice!

I would like to be able to group different dashboards into respective consolidated dashboards - which is kinda grouping like this but then a dashboard can belong to different groups.
