Hi Sean,
Really happy that you're enjoying the software so much. I have to say I'm probably in exactly the same place. It is SO SO close to working perfectly. But not quite there. I've come to adjust to doing a double pen tap while switching and I've avoided those little pen nicks I used to leave on the screen.
Getting it to the stage where it immediately switches is the goal. There is a chance that there is nothing that we can do after a certain point. However, we don't know when that point is going to be reached so we are going to keep shooting for perfect.
