Misc. notes

On flow

A reader needs flow hints to know which way to page/scroll through text (multicolumn text, RTL and LTR languages, books with "blocks" of content broken up across the screen, possibly of different sizes as in comic books). How do we embed these flow hints within book files?

Balance between artistic freedom for graphic design (okay, do you /really/ want to have to nudge all the pixels in by hand? like how folks used to set slugs in type?) and standardization/readability; css/skinning can look great, but it's also very "standardized" (unless you introduce deliberate randomness?)

On chording

How many buttons can we keep track of being pressed simultaneously? (Can we use chords as separate commands?)
