Personally, yes, I think the library is a better workflow. Maybe someone would add a one time tool to a single document. And maybe they'd even use that tool later in another document, in which case they can select it from the first document. I imagine this may be more valuable if I was sharing the doc with someone who didn't have my library but did have my tool. But I would think in most cases, and in all of my cases, I have a machine and a set of tools in the shop. Those tools aren't tied to any particular document in Fusion. The library represents the actual tools in real life in the shop. In each document I refer to the tool. I wouldn't change the tool in the document because it's still the same tool in real life in the shop. I may run the same tool with different speeds, for example, but that is set in the individual operations. The more tools I have, the more it makes sense they are managed in the library because otherwise I have real tools in the shop but I can't remember which Fusion doc they exist in. I would just like the default to not copy into the document. I could think of plenty of fixes/features that are more important though. 😉
