Feat request: more variety of color across language features in JavaScript

[trusktr]

Thanks for this theme! I have a license.

Some languages have more variety than Monokai Pro, which makes some syntax nicer/easier to discern visually.

For example, here is Monokai Pro where we can see decorators are the same color as field names:

Here is the Plastic theme where we can see decorators have a different color than the field names do:

The Plastic theme also has more variety of color in other areas of syntax, which is one reason I like it. For example see the exports vs static in the screenshot.

I enjoy the Monokai Pro palette design more, but would love more variety.
