The iOS version is so good. Is there a reason you wouldn't simply model the Windows version after it. I am a long time iPad Pro user and Goodnotes iOS user. I recently am switching to a Surface Pro for other reasons and will be sad to let go of GoodNotes. I am currently using the BETA version for windows but it is very limited in comparison. For me, usage would be the same whether I was on an iPad or a Surface. Thanks.
