Note: Replit now supports custom themes within the app itself, so this plugin is hereby deprecated :)
Allows customisation of the repl.it color scheme (syntax highlighting).
To install, download the repository and extract it. Go to the chrome extensions page and enable Developer Mode, then click Load Unpacked and select the extracted repository. Change settings by clicking on the logo in the extensions bar and then clicking options in the drop down menu.
Make sure dark theme is enabled in repl.it.
Announcement on Repl Talk is here.
