In obsidian there is a community plugin called Advanced Appearance (could be wrong since i don't use obsidian anymore). My favorite thing about it was the color options. Deepdwn already has the accent color option (which i love), but that obsidian plugin had another option that would let you set the color for the background of the editor. something like that would be really cool for Deepdwn.

That’s something I’d like to add at some point, but it’s more difficult than it ought to be, really. There are a number of pretty ugly hacks in the editor portion that make color customization really challenging.

If Deepdwn’s editor is rebuilt in the future, it’s a feature I’d like to add.
