In Blender 2.8, if you have multiple objects selected in Object Mode, and then hit Tab to enter Edit Mode, ALL the selected objects (both the yellow active object and the orange selected-but-inactive objects) will be editable. This is new behaviour for 2.8, and while it certainly has its uses, it can also cause unexpected problems if you only want to edit the single active object.
So I'm wondering: is there any way to disable this feature? I can't seem to find one, but it seems too obvious an option to be unavailable??
