I use a dark color scheme (Monokai). When I work in 2-columns mode and have 2 open files in group 1 and 1 open file in group 2, it’s very ambigious what the active tab is. My proposal:
Make the active tab lighter, not darker, than the other tabs.
Don’t hightlight the active tab in inactive groups.
I’m curious to see if others share my opinion.

Formally known as Ramadanman and the head honcho of Hessle Audio, Pearson Sound is a key figure in the scene. He lays down a great selection, pushing the boundaries from garage to more deep house vibes.
