Hi there,
I don't know how about other people, but I myself use the : sign A LOT for smileys and sentences. And I know that I almost never use the " sign, which has a shortcut on the T9 keyboard (longpress the - )
I know it's hard for the developer to decide if he should change it, so that's why I'm running a poll:
What key do you use the most?
Thanks in advance if you want to take the time to reply!
