cool...

This theme is beautiful on Linux. I have it with my current setup, and I can believe how good it looks.

For me, this is the best theme.

Minimalistic and neat. Thanks.

The "Matte" Theme is eye-catching. Nice name, Great idea to make it a series of themes with more colors for the tabs. Your red one is the most successful. Can a slightly less black version be had in the future? rgb(38, 38, 38) or rgb(51, 51, 51) for example.
