Hi there 👋

Problem:
Now Oxygen Builder supports using CSS variables, but it does not show color preview.

Workaround Solution:
Import all stylesheets inside Editor.

Potential risk:
CSS collison with Editor, breaking few things. If collision happens you can use Quick Fix to remove it from Editor.

Potential better solution in future:
Marking stylesheet with color variables with some special comment /##COLOR##/ which could make parsing easy. So if stylesheet is starting with that comment it will be pulled inside Editor for eg.
