Are there really no way to truly close apps with the "OK" button?

Hey MBartels... not sure if you found your answer and not sure if this is what you meant, but using Handy Switcher (I am also a fan of this software) you can use the OK button on the side of the mogul and it will close any open apps. I also map the "show menu" feature to a hardware button and I use it to show all open apps and can use my right directional button to close it as well. Hope this help in some way.
