Another feature I'd love, although it's less urgently needed for me, is the ability to customize the line spacing independently of customizing the font size. If I set the font size taht's comfortable to me - 85 in InDaisy - then I only see approximately 7 lines on the screen (iPad in landscape mode). If the lines could be closer together I could see more lines of text which would help me a lot. I know for some low vision issues, though, 7 lines would be too much and wider spacing would be needed - hence my request that it can be customized.
