This has been a nuisance since the original iPad 12.9... The font size is just far too big when the whole screen is used for Safari in Landscape mode. The solution? Have an app (e.g. Mail) open in ~1/3 screen size, which shrinks the font in Safari. But still, it would be nice to be able to shrink the font without having to have an app open to the side. Anyone else agree with me, or am I the only one with this want?
