I still would need a way to inject code that could catch the user touching a specified field and create a password box. It seems like there are 3 main steps
1. figure out how to intercept the user's touch
2. create a dialog that receives and checks the password
3. some action that will make the books accessible after the password is entered
For 1, we could
use the GUI launcher, but then might as well use the folder hider plug in instead.
