IPad pro as graphics tablet

You can set the iPad to show the Animated CC or Kriat App on its screen, and then use the Apple pencil to control the app. It may work for you to draw and control some actions on screen. Whether that is enough for you only you can say.

I’m never experience Animate CC or Krita on iPad Pro before. I ever run Premiere Rush on iPad Pro 11” 2018. In my opinion, it only work for a very simple task. I tried to edit 13min Full HD video taking with my iPhone XS, It work but not that smooth. Also, to render this file in 720p it took about 1hr. So i not recommend for work station replacement. But as a second working tools, it work well.
