Android HTML viewer: need Advice

[EightBitSensei]

Hi, i'm working on an Android application that will allow the user to view source code of a given URL address, I'm having no technical issues but I need some advice on what features I should add, I'm adding a feature that allows the user to favorite a piece of code and save it, but other than this I've run out of ideas does anyone have any good ideas for features?

I teach Web development. In order to check assignments, I usually need to see the source code of the page. What I need most is good clear type that can be read easily. I'd say that providing options for font size and perhaps font face would be great.
