I just came up against a problem and I am curious as to how other people tackle this in their Kicad workflow. I have a few circuit "blocks" that I want to reuse across multiple pcbs (e.g. switching supply layouts) and sometimes multiple times on the same layouts (e.g. multiple amplifiers all with the same parts and layouts for consistency). What is the easiest way to reuse and duplicate layouts? And how are people doing this in a way to keep things in line with schematic layouts? Cheers.
