Im still using the Kindle Fonts also. I am reasonably happy with it, but for one problem....
The sizes... I really wish there was a size between #2 and #3 fonts.
I have no idea what the sizes are, (I would assume 36,24,12,11,10,9,etc.)
Is there a way to add a new size or change the sizes of the stock fonts? (Assuming the sizes I listed are correct, I want to add a 18)
