This is very nice

Further, one needs often scroll this window and it size is bounded from below

As an author I would like to have a control what will be in the
Spyglass window.

" for printed article" I wrote. As far as pdf article is concerned if
your page is clogged by old equations then you have very little of new
material. Therefore this trick should be used not too often and thus
pop-ups or Spywindows or Copy-paste are required

The problem with Skim or any pdf-viewer different from AA/AR is that
they are not full-featured and cannot display JS animations, or
movies, or u3d files. The latter is not exotic anymore: Mathematica
can export to PLY, Maple+Javaview to OBJ, Meshlab can convert both PLY
and OBJ to U3D (the color is lost so far)

Yes and the same is true for fancytooltips but even in the worst way:
even without JS hyperlink is blocked

Well, none of this is truly correct behavior IMHO. A reader should be
able to chose between following link and popup without enabling
/disabling js

Will they listen?

Yes, as long as AR is not required due to multimedia content
