Thank you for the compliments.

That is not the panelwidth, but the lowest panelwidth one can
have. You can increase to any level.

It is trivial to make the lowest value allowed for panelwidth to any
desired value. The question is -- does that serve the purpose.  In my
experience, going less than 15% of the screenwidth can cause bizarre
results, that is why I hard wired it to a minimum of 15%.  

Those who don't need the panel can choose 'nopanel' option. Still you
can have the navigation buttons as tiny stuff in the bottom with the
command \bottombuttons.

It is still there. You need not tweak the overlaywidth at all. It will
recompute widths/margins and will automatically adjust. But you have
to provide all the commands that change dimensions before \screensize,
because, it is this function that does all the recomputation work.

No, that is because, you changed dimensions after \marginsize.
pdfscreen doesn't recognize changes after that.
