Found via TidBITS, this is an absolutely brilliant idea. I want and need this yesterday. To stay on top of my life, I feel I spend a lot of time launching an app, checking its contents and then moving on to the next app. This is the perfect solution. It just needs a to-do list (either sync’d to To-Dos in Mail/iCal or, better still, something that OmniFocus can insert it’s to-dos into).
