Define color for INSTANCE in addition to GROUP
Is your feature request related to a problem? Please describe.
The new feature introduced in 2.4 to apply a color to the header for a group of instances is great but could be much greater. As a user what I really want to be able to differrentiate by color is DEV vs. PROD. But I also want to be able to be connected to both DEV and PROD at the same time and compare objects between the instances. By creating different groups for DEV and PROD I can assign different colors but this takes away the ability to connect to both at the same time.
Describe the solution you'd like
In addition to the group color feature I would like to be able to define a color per instance which would be applied as the background color of the tab for each tab which is opened. This would make it much easier to differentiate which view belongs to which instance, especially if instance name is not displayed in the tab caption (which I never do as instance names are quite long).
