Dark Mode Suggestion

Hiiii. Here with a slight adjustment suggestion. As the dark mode is currently, it's actually quite difficult to read with #444 as the post background color. I've noticed that my eyes strain more than they would with a slightly darker grey. For this reason, I'd suggest a color such as  #2f2f2f instead of #444 just so that it boosts that contrast just a bit more.

Also, in dark more the text color in the editor is the light gray against white and is a massive stuggle, so I don't know if that's a possible fix too but it would be great <3
