It sure would be handy to keep a project organized if you could right click on any project tree item and move them up or down its subtree level (additionally, copy and paste from one location to another would be even better. Even if only basic structures and values can be pasted (no selected faces pasting if they don’t exist on pasted geometry)).
Things like Geometries, Meshes, Primitives, Refinements, Simulations, Simulation Runs, Boundary Conditions …
On the topic of Refinements, does the order in the sub tree matter, could Inflation precede a Region and Surface? Or does the meshing algorithm try to do them in order?
