How to dark theme Slack v3.x and v4.2.0+ (and not just the sidebar)
Update as of 12.08.2019:
- ** v4.2.0 update brings a new .js file to update. Instructions below are for versions 4.2.0+.** Update as of 11.27.2019:
- ** Revised styles for a Solarized'ish look.**
- ** Animated message input with showing/hiding formatting bar. (I didn't like the new, bigger message input area. So now it grows only when needed. :)**
Slack's themes really aren't that great. You either get Light or Dark, and then some Sidebar themes. The main content area just stays boring if you "theme" it using Slack's default ways.
