I just like black so I can see my menu bar and the shine it gives.

OOoooo....i love it...

Приятная глазу простая и красивая тема.

For using as a libreoffice theme, it really looks excellent.

I use this theme from few years. With Firefox 57.0b14 there are a bug : Toggles buttons on find bar doesn't show as buttons but as simple text.
Edit: it's a Firefox bug: https://bugzilla.mozilla.org/show_bug.cgi?id=1414693

Metallic Black and Red are so realistic here. Congratulations!
