Hello Von,
After having the same tragic response to hitting the home button in the middle of a great game never to find my way back, I went on a mission of engineering several complicated models to finally end up with just a simple metal binder clip.
At first I used the smallest one and removed the top swinging handle, and replaced it with a guard made from a paper clip that swings out of the way when the home button is needed, however my freaky fingers actually found a way to still hit it.
So I now have the next size up metal binder clip (2nd to the smallest).
After carefully clipping it over the side of the tablet with the home button, I then simply remove the handle that's on the face, and then replace it when I need to remove for charging etc.
Please keep in mind Im on the ipad air, and the binder clips are perfect size for this tablet, also I did un stress the clip just a bit by opening over a round tool to make it have a little less pressure on the tablet screen.
Hope this helps Von to stay calm, any other questions please feel free to ask my fellow Dogfighter!
Have a great day, and happy killing!
