[Helpful Hint] Double Doors

I know this will get buried in the depths of r/Minecraft, but this is to address the "problem" with double doors. If they are closed, the left door (while looking on the outside) is programmed to open both doors if double clicked. This is reversed for closing. Just double click the right door (again, looking at it from the outside) to close both. Now, I'm not saying this is a brilliant design, but I'm tired of people thinking it is a bug.
