Well, time is also an investment (grin). I too prefer the Bryce interface to Vue 3 though I suspect this is only because I am used to it. It was still a thing to be learned so is less than intuitive. Vue 4 apparently now uses a similar "trackball" for movement and entries that were formerly numeric only may now be interactively manipulated. In fact, many of the adjustments seem to be more interactive than in V3. These are some of the changes that make me think Vue is becoming more Bryce-like. The material editor is certainly less arcane than Bryce's and you can actually create your own material and other preset groupings, something which I am not sure has been finally incorporated in B5. I really am having a tough time deciding which way to go at the moment. Fortunately there is no need to rush.
