Paul:

I have not yet been able to re-create the problem you were experiencing but I agree that speed-reading needs some re-vamping. At the very least I will try to rig it so that only the forward arrow changes. Or maybe I should make the backward arrow under speed reading mode work back along cards read (as opposed to working back through the current volume). Or would this be too confusing?

ANYWAY, this too is now on my official list of things to do along with the personal link buttons and separate card windows.
