WIP Interactions in Focus mode

We will allow to interact with objects with constraints while they are in focus.

A new Edit mode (triggered by a button) will allow to interact with the focused object:

• If the focused object is a rack
  • rotate on y axis
  • translate along y axis
• If the focused object is a device
  • rotate on x, y, z axis
  • scale

For children of the focused object

• select (with single click / touch)
• translate on x, y, z axis (drag / pinch)

Inputs in Edit mode are to be defined

Edit 11/05:
In XR versions, use Bounds control for modifying objects:
