Explanation of MANIFEST File
This file changes the apparency of your World Editor to your Window's Theme, if you look closely to your World Editor you should note that his apparency is equal to the Window Classic theme. This file allows your world editor to follow your Windows theme. Smart huh? Like you can see in the screenshots users have submitted, their world editor classic theme changed to their Windows custom theme.
I hope you learned something,
