I am trying to replicate a theme that I love from VSCode within PhpStorm. The theme has glow around class names, and I'd love to try to replicate it! The only place I can see to add any type of effect is under Preferences > Editor > Color Scheme > Language Defaults, but it's a set list of effects that are mostly underline/strikeout/etc, and I can't add my own.
My favorite thing about VSCode was that you can create a theme using just a CSS sheet that you import. Is this possible with PhpStorm as well? Or is it possible to somehow add my own effect to the list of available effects under Language Defaults?
