VerticalLayout group child size options really needs to be non-destructive

Layout groups drive me nuts. The biggest problem is when you toggle child size options (force child expand etc.) it goes and writes a new size value in all the children. If you uncheck it, it doesn't restore it to what it was (or what the prefab value is). So your entire GUI is destroyed unless you remember the original value and to back and paste it into each width/height member.

Can you guys just fix this? Can unchecking the checked option just act like an undo and change the sizes back to what they were before you checked the chidl size option???
