I don’t think this counts as a plugin and I’m way out of my own depth. But it could be interesting to use a personal database to generate a sort of procedurally generated mansion which you could then wander around and use corridors to move between notes. A sort of memory palace to help reinforce and reframe ideas.
The rooms themselves could have certain attributes depending on the title and contents of the note.
Nice. I am happy to see this idea and would definitely welcome it. Being pretty old school when it comes to occasionally disconnecting from the computer, I think there is potentially an opportunity for some sort of middle ground. Mixed reality Graph View integration
In my link, when I say VR doesn’t seem too attractive, I am only talking about in the context of my idea. VR would be great for what you are envisioning.
