New in 1.2.2
• Each system on the canvas can now have its own load. Select a system, open Settings, and set a load just for it — all other systems keep the app-wide value.
• Settings is now split into "This System Only" and "All Systems", so it's clear what each change affects.
• Fixed: changing the load now updates anchor forces and pull force right away, instead of only after you move a point.
