[Prime] Is it possible to install larger display fonts?

[chromos]

I vote too for bigger font overall. I am using android Prime only and text in its current biggest size is hard to read on 6" screen (calc diag is 2.9" [74 mm]) even with glasses.

Matching Prime proportions to phone screen height/width ratio
Black and silver margins are 0.55" wide [2×7 mm] which is almost 20% of calc screen. It is completely useless waste of space. :-(
