This would be great. To add to this, it would also be a lot of fun to have the ability to filter a particular type of note unless it has X number of connections.
For instance, I have ~50 books I want to get to reading in logged Obsidian, that I normally have filtered out of graph view so as not to clog it up.
Being able to use a filter query like:
-tag:books(unless5+connections)
would be a really useful way to naturally track with graph view which books become most relevant to me as my notes evolve.
