I also wrote about this here: Context Overwhelm, Concentric Vaults, and Sensemaking - Thinking On Thinking In Notes
I still think functionality along the lines you suggest is necessary. For me, at least. I have been poking at a potential solution using plugins, but I haven’t had the time to get it working. I’ve managed to duct tape a system together with scripts that copy or sync vault stuff around, but it’s fragile and takes too much setup.
I definitely support this idea getting some deeper thought.
