Now a subassembly xml has to be directly into the Subassemblies folder. For subassembly packs (like the ones we are using for Real Engines) that makes a mess.
We try to name all mod parts with ( name code ) so they are all in the same place, but once you add many it's hard to find them and delete the packs.
Could you add the possibility of sub-folders so we can just add one called for example "Real Engines" and get the files detected?
I'd advocate for sub-folders for normal craft saves as well.
