The light theme sure does look pretty but it'd hurt my over-sensitive eyes after a few minutes. I will however for sure check out the darker version you showed in a different reply. My main pc's desktop is ugly right now because I just use it to get stuff done, but I wanted to change that for some time and I'll give this theme a test drive :-)
i have two other screenshots (those being in biscuit-dark), but they are exactly in the same way as the biscuit-light one (same window placing, except the tab open if LibreWolf)
