Fixes and enhancements to right sidebar

• All panels expanded by default:

  All settings panels are fully open when you launch the builder. You can then collapse any that you don’t need. Previously, some panels were collapsed, which made it difficult to view all categories on one screen.

• Switch to General whenever a new element is added:

  New sections and elements that are dragged and dropped will automatically open the

  General

  settings tab. In the past, the previously active settings tab remained open.

• Reordered controls:

  We have reorganised some settings panels for a more intuitive flow.

Fixed an issue where the width setting for the button and video elements wasn’t displaying the correct preview in the builder.
