Remember the active panel between the instance properties and the object properties panel

[Bouh]

Description

Since the object dialog is almost useless thanks to the object properties panel I'm facing trouble with the switch of instance/object properties in the same panel.

I'd like the app remember in which properties I am, even if I'm clicking on another instance from the scene.

Solution suggested

Remember the active instance or object properties panel accross.

The solution could be to add a new button on the object properties to "Edit the instance", and to disable the auto switch of panels.

Alternatives considered

We can select the object in the object list panel, but when there is a lot of objects and the object you're looking for is in a folder we can't see in which folder the object is located (because there is not highlight on folder when an object from inside is selected on scene.), so even this alternative doesn't help.
