This plug-in is great! Took a little bit of customising to get it to what I had envisioned, but, the functionality is all there! Good work!
I am currently looking into how I would go about adding some additional buttons like "skip to page 10". I am happy to code the information myself, but I was wondering if you would be so kind as to point me in the right direction as to where the original button coding is in it's php file?
I will be requiring to place 3 separate books onto the site I am designing, so I will be looking into purchasing the additional version upgrade in the near future.
