Completely satisfied!

Well this is one of the best app i have found to add notation on my pdfs, and thats all I was searching for. There are still some minor bugs, like the accents (when I add a note and export it to my google drive, they are not showing), or the arrows or ligns (move or disappear during the same process).
But still, very good for a free app!
