Figma Support Forum

Suggestion: Support figma.ui opacity

When a web or mobile engineer implements a page based on a design, many of them will overlay the design and the actual page to check for differences.
I tried to create a plugin that would do this, but I could not make figma.ui transparent.

Being able to pass opacity as an option in figma.showUI would help a lot of engineers.

For your case it would better to just overlay an image on top of the inside instead of using your plugin ui as the overlay
