Preventing iPad Pro from getting hot during usage
A strange way that I've gotten around this issue is by placing the iPad on a large heat sink—basically anything that can conduct heat really easily. An example is a laptop (that is turned off!) which can take in a lot of the heat generated from the iPad's body. The iPad needs to be placed in direct contact with the heat sink.

This actually significantly cools down the screen of the iPad, which allows me to place my hand comfortable on the screen while writing. It's still warm, but at least not burning hot.
