Björn Waide's dashboard

Being productive means being focused. Unfortunatley I tend to switch quite often between my "productive" tools to email and back again. Or to the browser to start reading an article, then deciding that I should do that later and so forth.
I'd be great to have a report that tells me for how long I've been working constantly with(in) a single application. And I'd like to define goals or alerts for being "focused".
