In 2.11 beta 15, the "Auto" button in the Door Combo Set editor does not work.
Beta 15 Door Combo Bug!
Still is sorta flaky in 528, adds some things sometimes, other times you gotta do your own legwork.
What is "auto" suppose to do?
I believe if you add the first door, like a shutter>open, and hit auto, it should fill in the rest based on what info you gave it, but it doesn't seem to.
It sometimes will fill all the tops in, and other times not for some reason.
It doesn't harm anything not working, but it would be a big time saver if it did.
Fixed in the next build.
