I’d like to suggest a feature improvement for Figma based on a recurring pain point I’ve encountered.

When creating a modal (popup) component, I often need to display the background content underneath a semi-transparent mask. Currently, this means I have to manually copy content from other Frames into the modal component. If the original background content changes, I have to go back, delete the outdated version, and replace it manually—this becomes inefficient and error-prone.

I’ve tried making the entire page Frame a component and then inserting an instance behind the modal, but this approach feels clunky and unintuitive.

What I’m hoping for is a more elegant solution: a dedicated “Backdrop Container” or “Background Mirror” feature within modals. This container would let me configure a specific Frame and automatically mirror its content beneath the modal mask—keeping it synced with the source and reducing repetitive work.
