This isn't a request, so much as an idea. It might be cool to add something like themes, skins, a way to change the writing enviornment so that it looks and feels a bit different. It's cool to have light and dark mode, those are necessary features. But it could be interesting to have a slightly different background, or different options to choose from, to spice things up, get ideas flowing, that sort of thing. Example: you could have bookshelves in the background, or stars, or different colors of patterns. Something lightweight and not too obtrusive, but just different enough to change on the fly to suit a mood while writing.
