Strange thought but hear me out.
I am not really serious. The whole world is too attached to their mice, but this is what I would like to achieve: to be able to drive all applications from the keyboard with out having to resort to moving my right hand 15 cm to the right to grab the mouse to have to click on a button or menu item because there is no other way to activate the action.
As I mentioned in my recent UI Musings post there should be several ways to achieve the action I want to achieve: Menu item, button and shortcut key.
This is all very easy to achieve and it annoys me when applications don’t provide shortcut keys. It annoys me even more when the same action has a different shortcut key for the same action on a different screen.
This is even achievable even with a web application. Look at Google. Reader, gmail, calendar and a host of others provide shortcut keys for the most frequently used actions. This makes for ease of use and enjoyable user experience. Granted some of these shortcuts take a little while to learn but once you get them down it makes for faster navigation.
These things are the 20% that remains after the 80% that matters has been completed. They are ‘nice to have’ but they sure do make applications easier to use.
