Corporate email aside, I've added two new dark themes so far, one red and one purple, I'll probably make more (light and maybe dark) later. If everything worked, you're probably already using the new Blood-dark theme, feedback on it and Royal-dark is welcome.
(To change theme, go to settings, paintbrush icon, select from the dropdown menu, and hit apply)
New favicon should come tomorrow, and I also want to figure out how to set the logo to be a mask for better light/dark compatibility... not working that well right now. not as important either.
