Feature Request - Groups & Sorting

I have numerous entries in my server list. Have you thought about allowing for creating groups?
And to allow sorting? It's getting harder and harder to maintain the server list.

Example:
Unix Servers
...Server 1
...Server 2
Microsoft Servers
...Production Servers
......Server 1
......Server 2
......Server 3
...Development Servers
......Server 1
......Server 2
