-I have a dual pen (i.e. I can write on one side and erase with the other) but the app is having trouble of switching back in time. When I erase and go to back to writing, it ends up erasing
-Page lag; takes time for page to load with writing
-App freezes sometimes (I don't know if this is just me or due to too many notebooks used but after deleting some notebooks I have noticed less freezing)
