Active mode is hard to identify

The only thing that marks the active mode in the Light (2024) and Dark (2024) themes is a green line directly at the window border.

This makes it very hard to see the active mode on a glance. I am regularly lost if I am in Debug mode or Edit mode, which otherwise look very similar.

This is especially bad in the Light mode where it is a light green line on a light background. If there is any other content from other windows visible at that border, the line just gets lost in background noise.

It gets even worse with stronger glasses which introduce chromatic aberration to periphal vision, which makes the green line actually wander out of the window completely.
