Interval timer - with visual time display - like time timer would be useful to keep us motivated and moving to also make us more productive.

the visual time display of time timer i find useful - and can also be made linear with a bar type timer that could sit below the url box in the browser and act as a visual timer - little sounds could pop up that keep us moving on what we need to be doing - like we could set a ding every few minutes - every 10 minutes - heck even allowing us to set a goal for the next 10 minutes would be useful
