Click label to invert checkbox, widen Ribbons so 5 appear per row, reduce margins.
Casting issue, OfType to get all Checkboxes because the foreach doesn't auto filter the Control[] to CheckBox[]. Thanks Armodillomatt12! Also, don't forget to actually save the changes back to the main save file...
BW vs B2W2 will prevent flags Defer layout when adding controls (increase speed).
