Better CSS request.

[setanarut]

i'm qlmarkdown user, i'm using my own dark css where i follow apple's dark mode guidelines. I tried this plugin, it's a nice app, but the contrast of the markdown theme is very high and it looks almost black and white on dark mode. Causes eyestrain. it would be nice if it can be customized with css or to use qlmarkdown and glance at the same time. For this reason, it's not possible to use this plugin. Thank you.
