Kyle // OperatorRazzI changed the colors of the Mastodon compose box to fit with the dark theme. Also stylized all of the sub-menus. Much better. You need a browser stylesheet extension (like Stylus) to get this to work. Before/after pic.
I uploaded the stylesheet to UserStyles World.
Small edit required - If you're not on the mastodon.online, mastodon.social, or mastodon.gamedev.place instances, you'll need to edit Line 11 with the instance you ARE on. Simple instructions in description. Stylus (or similar) browser extension required.
