You know how in Safari for Mac OS Lion it supports a cool feature to zoom in? To do it with the Magic Mouse, just double tap. The page zooms in to whatever part of the page you’re viewing. This is basically how it works on the iPad and iPhone too. Just double tap and you’re set for a more readable experience.
Mail for the Mac needs this. Many people use large desktop screens, and when you’re in Mail the text of various email messages might appear very small and hard to read. It would be very intuitive if you could interface with Mail like Safari: just double tap the text and it should enlarge the text within the Mail window.
I can see that the U.I. of Mail doesn’t work the same as Safari’s. Since it doesn’t maybe there’s a better solution, but there’s gotta be a way to use the mouse to make this trick happen. The most effective way to do this now without a mouse is to use the keyboard—pressing Command and the + key. But this is tedious when you’re already at the mouse.
Now this is a mighty mouse. It’s symmetrical, ambidextrous (suitable for lefties and righties), comfortable, ergonomic, gesture-capable, and universal.
This ought to be built into desktop browsers now. I’ve grown so accustom to this function on my iOS devices that I impulsively attempt this on the desktop computer.
