Fixes and enhancements to right sidebar

Enhancements

All panels expanded by default:
All settings panels are fully open when you launch the builder - then collapse whichever ones you don’t need. Earlier behavior, some of them were collapsed to show all categories in one screen.
Switch to General whenever a new element is added:
New sections and elements which are dragged and dropped automatically open the
General
settings tab. Earlier behavior - Keep the earlier working setting tab open.
Reordered controls:
We’ve shuffled and organized some settings panels for a more intuitive flow.
