I don’t usually need help finding connections between ideas, to be honest. If I read a piece of information usually the first thing I do is “ohhh, this relates to xyz and I could use it as a basis for abc.” Or “ohh, some other person agreed with this, I’m pretty sure, I should cross-refetence with that other culturr to compare and contrast.” I live in a mental landscape that is rife with connections and analogies and don’t typically need more than graph view or a quick search to notice things along those lines when I’m trying to make sure I haven’t missed a connection about a topic. Maybe that will change as my vault expands, but I’m rarely trying to “generate” spontaneous connections and ideas because I already have a pretty lengthy todo list based on connections I picked up on while reading and performing daily review of my notes. Other people who have more experience with that goal will probably be more helpful, there.
I like the idea of the Journey plugin for people who have a different process than me, though! It basically walks through your notes – you select point A and point B – and finds a path that connects them and turns that into an outline for you.
