^^^^ Yes font hack is awesomeness. Can't live without it. Many thanks to NiLuJe and all the devs for their work and answering questions,
Maybe it's my dumb luck, but I've never had problem overriding fonts. I override Baskerville, Helvetica, Palatino, Condensed. I even override Futura, which gives me easier to read library and menu screen. Not that I recommend people do this
