Summary of the new feature/enhancement

My feature request is the following: Currently, there is this huge tab at the left of window Title:
https://i.imgur.com/NkCGn3f.jpg but the problem here is, that I am using an accent color that overwrites the title bar for every application.

So I wanted to ask if it would be possible to give us a feature, that we can change that the color of the title bar on the left to the other color, or at least a feature that it automatically gets the same color as the accent color.

Thanks for reviewing.
