A few remarks:

(1) The mkiv approach uses not that much javascript actually, it uses 
layers that get turned on and off and it has a simplicity that i like, 
also because there is no interference with repetition (e.g. of 
references) cq. are no side effects (like bad spacing). Unfortunately 
layers are hardly supported and the trivial javascript to control some 
aspects of viewing neither. (Luigi and I have been thinking of adding 
lua to a mupdf based viewer ... maybe we should pick up that thread.)

(2) Steps i.e. repetitive content has the problem that one then needs to 
make sure references get flushes only ones which also demands care by 
the user, and spacing not be influenced too badly by redoing chunks. 
This is why I made some explicit steppers (there are some in the mkiv 
part as s-present* files).

I can give it some thought but it's not that trivial to do it right 
(according to my specs).
