Active Viewer window tabs

Hi
Natron novice and some confusion with the interface. You notice in the attached screen shot that even though Viewer 1 is active it is extremely difficult to tell. The window tab for the active viewer needs much more contrast. is there a way to enable this in the preferences?

You can name each of the viewer nodes by selecting it and press the letter ā€œNā€ and type a new name.

Thanks, yes aware of this. But my question pertains to the viewer tabs for the active viewer.

That feature will require some implementation. Did you know that you can merge viewer windows to show there inputs side by side. Plus you can sync lock them together to resize them and sync lock them to the dope sheet and curve editor.
