 I would second this. I think OM designers should seriously consider
this suggestion.

 +1 for this one.

 Bigger font sizes is a good option especially for mobile phoens. I
remeber I used to strugle a lot with small font sizes on my Motorola
linux based smart phone.

 Another good suggestion. Also I would like community/OM designers to
come up witha  theme suitable for colour blinds. People with color
disability form a considerable number of mobile users and notice them
struggle with mobile phones all the time.
