I'm not maintaing this theme anymore. I don't know if it will work on newer versions of joplin.

VSCode Community Material Theme for Joplin

It's not 100% identical and there are rooms for improvment. Mostly background colors are changed and everything else is Joplin's default UI and your system default font.

This theme is a modified version of Joplin Light Theme by LongBay originally Joplin Clear UI theme by Marc Teyssier.

How to Install

Enable one of the dark themes in joplin and copy userchrome.css and usersyle.css to your joplin config folder. in GNU/Linux ~/.config/joplin-desktop
