Thanks for the quick response.
I had already searched plenty, and my continued searches have not been helpful either. I've tried the formatting in
this link, which Kovid himself had shared in one post, to no avail. I've tried converting the epub to an epub v3, and no luck either.
I posted in library management because I saw that it says "All about viewing, adding, and exporting books". I now see there is a Viewer specific forum that this should have gone in. I can recreate this there, unless you or someone else is able to move it wherever is appropriate?
