@haimingz: nice theme, I like the amended Andy Mode. Like @Mayonnaise2124 I use the scrollbars for the same reason, though I agree with you that in short, atomic notes they are extraneous. I have a zettelkasten with atomic notes, and another note set with (very) long notes.
I find the dark version not too dark because the background is not black, it’s more like a very dark grey.
Well done !
