"Dark Reader" Chrome extension, for example, works on every site I've ever been to in the past 2 years... except PF's developer.playfab.com
I believe this is due to too many "important!" CSS flags that override extensions.
If you folks don't have immediate plans to release a dark theme within the next month, it would only take a good 5 minutes to remove some of the important css flags to allow us to save our retinas :)
(PS -- if "Topics" are required to post here, you folks should probably also show a dropdown since common terms like 'portal', 'ux', 'qol' and 'ui' are missing. I have no clue what to put here, so just putting documentation)
