> a lot of software use node based UI Yes, and as pointed out in another comment, it does not scale well. It's nice for the "tweak" phase of - say - finalizing a shot in a CGI movie, but when you start to get more than a few thousand nodes in a setup, it's very hard to do anything. There are mitigation solutions, such as grouping and collapsing of nodes, but that only goes so far. Another annoying thing with node-based systems: - collaborative work is hard - version control is hard
