All I want is an iPhone contacts manager that looks like this:
See? It looks like the built-in app, except that for contacts with SMS-enabled phones, it has an SMS button that allows you to instantly compose a text. The button doesn't display a menu that asks you which number you want to text; it just lets you compose a text to a pre-set default. And the SMS button is nice and big, so there's little danger of accidentally placing a call when all you want to do is text.
Also, although you can't tell by looking at it, this contact manager lets you make groups and SMS the whole group. It's so got-dang simple. Why does this not exist?
