It would be pretty cool (I think) to be able to change the colour of the green highlight on the top bar and active links to match the colour of the selected area.
I have a few notebooks with the same name in multiple areas, and I quite often forget to change area when Im moving things about, for me it would be handy to see “Oh, everything is purple, Im in work” or “Oh its all green, that’s home”
Just throwing it out there as an idea
