Yeah, I'm curious too. If you use a desktop Windows app you will of course run into that kind of thing but there is apps like Sketchable available that are like what's on the iPad. Even on the iPad you can run into file save dialogs, from what I remember Clip Studio Paint on the iPad is for better or worse Clip Studio Paint on the iPad file save dialogs and all.

I tried a few. OneNote was good for notes but not for art. None of them felt as good as their iPad counterparts, plus I had to deal with Windows.
