A couple of times recently I have accidently selected 'Unload Unselected' instead of 'Load Selected' or some combination of this - very annoying that this can't be undone or reset?

In some larger projects where I might have specfic things hidden via 3D Objects from multiple imports, I've had to revert back to previous save as to not lose that logic.

Is there a way to overcome this? As description, just being able to hit 'Undo' would be great. Not sure what the limitations are on this...

Thanks!
