Font selection is dismal. Personally, I'm so totally sick of and tired of any and all 'sans' style fonts on all my apps, from every screen on most my devices. I want... Something else. Show me fancy, or bold, or striking, decorative, emotional, something... SERIF. Calligraphic. Brushed. Hand-written. Fck professional and clean looking.
Or give us an option to import our own... Like Chomp. Better yet, import our own font PER conversation.
I fully realize I speak for a slim minority of Android users, but sometimes, SANS fonts just don't cut it.
