colors by folder

this probably doesn't exist and is basically a feature request….

my data sources are split into folders - mostly they've been separated by scope - local database, uat, prod  etc.   Clearly it's valuable at all times to be really aware of what scope I'm working in - so I want to color each tab I'm in.   I know I can add a color to individual data sources - but I have _lots_ - and keeping those updated and picking the exact right colors is a pain.  What I'd love to do is be able to choose a color at the _folder_ level - and have the folder and everything underneath it have that color.   so if I move a datasource into that folder it just inherits the color for the folder - would save me a lot of work.
