Often I'm working on some nodes, and I realize I need to insert a new node into a pretty long chain of nodes. The result is a squiggly mess, and requires quite some work to bump all the other nodes along.
Wouldn't it be great if we could say 'Space out nodes' and it would horizontally space the nodes so that there are no cases where nodes need to squiggle, just because there's not enough horizontal room.
I seem to remember other requests for 'auto neaten' of nodes. This could be pretty complicated to design, so I think we could at least start on the x axis, per this Space-out idea.
