I’m not sure if this actually can be done without issues using css and html injection /javascript, but it would be great if its possible. I can help prototype, it would make the UI such much easier to work with:
The ability to drag-drop panels, minimize (pin) panels, but most importantly to allow an entity view panel to appear at the left, instead of always right.
Fibery currently enforces the breadcrumb left-to-right sequence of new panel creation. This makes no sense to me, and there have been some requests about this.
