On the contrary---I would like to disagree here.

Exactly---but this sort of automatic unlimited UNDO capability is a
wonderful thing for increasing interactivity. The higher bandwidth
of interaction you want to achieve, the more useful it becomes.

At the Geometry Center, we have just released a suite of interactive
graphical WWW applications based on fill-out forms, and have found
the automatic UNDO capability to be *extremely* helpful. Given the
turnaround time of network transactions, correcting or fine-tuning
one's input by taking advantage of the transparent UNDO feature can
greatly boost the apparent interactivity of the application. (Try it
out for yourself at "".)

I don't have anything against your proposal for "hints" that would
allow history to be discarded. I simply want to emphasize that the
default behavior of browsers should always be to *keep* intermediate
steps of the fill-out form.

Thanks for listening,
