Scrolling beyond 32k pixel limit?

Hi Mark,
I've tried one page per card. The trouble is that it is never as nice as the mobile scroller. The mobile scroller responds very, very fluidly, as you've probably seen. As your finger slides, the content slides right along with it. I haven't been able to figure out a way to use LC native stuff that responds like that. It doesn't seem impossible though...

But perhaps I can use such a transition to switch from one scrolling group to another. The reader/user might notice something odd every 32 pages, but I suppose that's better than a "Read more..." button....

I expect I'll have to insert a sort of "read more..." button at the "end" of group 1, hide group 1, show group 2, reset the scroll of the mobile control to zero... and continue on scrolling. Then reverse the whole process to go from group 2 to group 1.

All the navigation choices/options were held in a flat-file database, so edits and maintenance was really convenient.
