I get that, but it seems like that would be a deliberately unfocused type of usage. Todo lists can take any form and there's no shortage of apps or services that do exactly that, but they don't all necessarily set out to do anything more than be a list of arbitrary stuff. If I wasn't at my computer grinding through a list of computer work, checking a list would not help me focus on stuff I can't act on. If I needed a general list, I'd choose a product that aimed to be something like you describe.
