[Temanor]

Is your feature request related to a problem? Please describe.
You can not currently search for keywords in the CSS editor. This makes it hard to find certain classes when you paste in a long snippet.

Describe the solution you'd like
I would like to see a feature where you can search for keywords in the CSS editor.
Same as how it works in the browser.

Additional context
Something kinda like the one in Firefox would be nice.
