Yep, this is another one of my "famous" sweeping rewrites. Expect things to break. Goals for this are: - Greatly simplify node connections (particularly with arrays) so the code requires less maintenance/is more stable - Redesign node structure to address issues where UI would stall for lengthy periods of time - Less reliance on shared ptrs/greater reliance on QObject system for inheritance/memory management - General code cleanup and improvements
