Okay I updated the main thing. hopefully its more robust now.
works on my stuff. For what thats worth.
I have no margin hacks as you can see which tbh, works fine for me.
Sorry eips is not the perfect answer for this job, some swanky injection would be, but we all know how amazon feel about that.
Given minimum effort this is a working solution for me. I was just hoping to draw a few more people into tinkering with the works, it's really not that tricky.
There are certainly more involved solutions that could do a better job however POC of how to attach to each page turn with some crappy text is as far as I go I'm afraid.
