There is currently no option to save grids/guides that could be reused elsewhere.
For now I can only copy the frame that already has set up grid, but if I would have like 100 of them and wanted to change grid slightly then I would have to do this for 100 other frames…
Ooh yeah, I’d love to be able to copy paste guides. Or if you could save the guides (and layouts in general) in a component board that you could slot other elements inside. Right now you have to detach a layout component to place other elements inside it.
