Use Less CPU when in Background but Only in Edit Mode

I would like a new option similar to “Use Less CPU when in Background” which is in Editor Preferences/General/Miscellaneous/Performance.

The new option would do the same thing but only use less CPU in background while in edit mode and not playing.
Because I usually turn it off when debugging so that I know I get the correct values of everything and everything behaves normal.

Now when I am debugging things where the values of everything is important that they are as they would under a normal play session,
I just keep turning the option on and off all the time. Because I am still not liking my computer going on full load all
the time while just for example messing with some code.

So would like to have the best of two world :slight_smile:
