Better pdf eflow/formatting?

[DrMoze]

Is it possible that the formatting of pdf files (when changing font sizes) might be improved through a future firmware upgrade?

I'm borrowing several Adobe DE pdf's from the library. They look just like regular books (with big blank margins) at the smallest font size--which is too tiny to read when I wear contacts, even with reading glasses. (I can read them just fine with the naked eye.) (OK, my eyes are getting old along with the rest of me! )

When increasing font size, the big margins also disappear. But, page breaks are kept (so there are many partly-filled screens of just a few lines), and paragraph separations are often ignored. Could the pdf reflow routines be revised to be 'smarter' and better recognize more of the original pdf formatting to improve the appearance of resized pdf text?
