I think it would be awesome to be able to select a default tool on a document level that after a set period of time, or if the document is opened/closed that it would revert to. For instance, I generally use the calligraphy pen, but I also move my notes around a lot with the selection tool, and don't always remember to switch back to the pen when I'm done. I'll put the tablet down, pick it up to write in later, and start writing only to see that it's trying to select (nothing), and I have to switch tools and start writing again, which can be a little disruptive.
