I'm sorry, there is no real way of solving this :\ Because of how the game is made the fonts are rendered at the resolution of the rest of the menus and stuff, this means menu layouts would have to change to actually fit in bigger text, which is just too much work for us at this point. In theory you could do that yourself, change the font to a larger one and change the .gui files everywhere it doesn't fit, but tbh it would be a significant amount of work.
