Grouping websites in the hub

Hi wpmudev team!
I'd really love to have the option of grouping / sorting websites in the hub.

I have both, staging sites, new sites under development and published sites in my dashboard and I'd really like to be able to sort them / add them into different categories, just to make it easier to focus on the IMPORTANT things.

A RED WARNING can be completely irrelevant for a staging site - but definetly NOT for a site with premium support. Today I have to pay very close attention to these and it'd be a great timesaver if I'd just had to check 1 or 2 of a number of website groups, instead of all in alphabetical order, as it is now.

Best,
Malte
