When I think of all the unique ways that people format their notes both in terms of note and graph structure, I imagine that many would be open to share their system.
I would be delighted by any way that would allow this to happen. Perhaps you open the system template and everything is already there. Or, maybe you let it convert your current vault or folder. Even if it required a sequence of dialogs and/or fields to be completed, that would be all good.
Templates and the sharing of actual vaults are workarounds, but I see this feature as more of an engine to be tuned and less of city to live within. What I mean is that there is a lot of destination flexibility both on the creator and creator’s part, if you know what I mean.
