I was so excited when I found out that Goodnotes would be available on Windows. But I have to admit I was fairly disappointed. I would suggest that you make the app work between IOS and Windows smoothly. This means all the same features in both platforms. That being said, one feature I like in the IOS version that is not in the windows version is the ability to have internal and external links in the notebooks. Honestly, I mostly use Goodnotes for Planner like documents and the lack of this feature in windows makes it useless for me.
