What I do instead is write down in my little (edit: physical, pen and paper) notepad when I start a task then note when I stop it, later updating the timesheet with the difference. I just want to be able to enter a hours:minutes value for each task when I get a moment, does this app do that? It's literally the only reason I still use Basecamp Classic (v1)
Another pet peeve: If I click "Features" in the header or footer I want more information, I do not want to be scrolled back to the thing I already read.
