Ability to choose different fonts, or at least font size

The default font size is huge (on an iPhone 3GS, using iOS 5.1.1). It would be great if I could modify at least the text size, or if I could choose from a list of fonts. (Since the default one is outright terrible.)

The next version will have a font size option, added in 0098cc4

Stay tuned!

Has this been added? On the Iphone XS Max the font is very small making it hard to read on the main screen. I see no way to modify the text size. It seems the chat window when in a chat is dynamic and adjusts based on the default phone font settings, but not the main screen.
