anyPiP - Picture-in-Picture anything

How does this work? Isn't working for me. I wanted a notes app that worked Pip. Edit: It works, this is so cool. I am using it with Google Keep. For anyone curious about why I wanted a Pip. The idea is that while studying, I will create a list of keywords to backtrack and connect with. Similarly, coding, this Pip will have a list of ideas to be implemented.

work it!
