While it is very nice to see connections between different notes/subjects, it is somewhat lacking (in the context of graph view) that you can’t immediately point out what links two nodes together.
Sometimes you can recall just by association.
And sure, you can always get into the notes and figure out what gave birth to the coupling.
But wouldn’t it be nice if you could name a certain edge and have the name pop when you hover over it with the cursor ?
I think such feature would increase the value and usability of graph view significantly
