A BetterDiscord dark/black theme that boasts enhanced usability, readability, customisation and experimental features, which include...
Adding your own window title
Optional removal of Spotify Premium elements
Optional rounded or square icons
Blurred (or glass) popup backgrounds! (currently being redone)
...and much more!! (official powercord support coming soon)
I recommend you add an external RadialStatus theme -- RealDark can automatically configure it if it's present!
Newer configuration themes can be mismatched with an older base theme that supports them, but your mileage may vary if you do it the other way around!
RealDark Annoyances can be used without the RealDark theme -- just make sure to add and enable RealDark Configuration too!
Currently not available on the official repo.
