+1 but for everyone looking for a good dark mode plug in that doesn't slow Roll20 to a crawl (cough, cough, Dark Reader), there's the Tampermonkey Roll20 dark mode plug in. Just remember to disable Dark Reader (or whatever dark mode plug in you're using) otherwise you're not getting the benefit of the Tampermonkey speed. ETA: The exact plug in is the RedReign / Roll20-Dark-Theme. It's made specifically for Roll20. UPDATE: It appears that within the past day, Roll20 updated something on their end that made even Tampermonkey's plug-in no longer work properly. Your sidebars will be fine but if you open up character sheets/statblocks, it's this broken mess of half dark mode and half light mode.
