Is there a way to turn an app into a floating one? I want to search a specific installed dictionary app which is on my device while I'm reading a book in the Kindle app.  Is there a way to turn an app into a floating app?  Anything even close to this idea even exists?  

Note: I'm aware of pre-made floating dictionaries but I'm looking to use the one I have.

Kindle has a built-in dictionary that you can download. When you highlight a word, it shows the meaning to you. Is that not good enough?
