I'm not going down that slippery slope: If I would I'd spend more time working around other people's bugs than writing new functionality.

But YOU are perfectly free to volunteer your time to save Amazon some bucks: Take my epubs, patch them, and convert them to mobis that display the toc when you hit the toc button, and redistribute them on your site.

I had a car like this once. The turn signal was on the right side of the steering column.
The headlight dimmer was on the left side. The window winders worked backwards.
The inside door locks would lock when you pulled them up, and unlock when you
pushed them down. An iconoclastic car' which was one reason I liked it. No
concessions.
