Difficult to discern between pressed and unpressed buttons

When running in darkmode it is difficult to see if a toggleable (if there is such a word) button is pressed or not.
This is especially true for the Show failing tests since you dont know if there are any.

This is probably a fair observation. The original dark scheme was modeled off an older VS layout that probably shared this problem. I can see they've addressed this by adding a blue border to the selected buttons. I'll take a look to see if there's a way to improve it.
