Not obvious enough at first glance what servers are in a folder

Hey, quick suggestion. It's not obvious at first glance which servers are part of which folder when you have the folder expanded.

I suggest using a variant of the color of the folder as the background color of the folder container. Example screenshots below where I edited the css to show what I mean, but I'm sure your designers could come up with something nicer :)

I often find it hard to find the server I'm after when I have multiple folders expanded, and I think this would help a lot! Thanks for coming to my ted talk.
