The menu button in the conversation view would have a settings shortcut and a theme option. The theme option would take me to a page where I could individualize the colors and background of the previously selected conversatin. And be able to save a different style (colors and/or background image) for each conversation. And maybe change the way the conversation list slides back into view. So instead of swiping and thenn having the list slide over, have it be so as I am starting to swipe to the right the list is coming into view. Both of these ideas, I think, would really add to the experience of this amazing texting app.
Thanks,
