Arc Dark (with inactive window fade)

I like this one better than the other one because you can actually tell which window AND tab you're using. That's very handy when using multiple monitors and you actually use all your space.

Simplistic and dark. Looks fantastic!

Nice dark theme, but with tabs you can see. Most dark themes are so dark on the tabs that you cannot pick out the next tab, but this one has the next tab in grey, so easy to see.
