What's Your Favorite List Manager?

I use it for at random check lists, as well as the context bas base list, you know, at computer, in car. I have one called horizons of focus, and it contains s all the way from the 50 thousand through 20 thousand foot level. And then i've got a set of wonder list. Has a cool feature of these folders, so you can take lists and sort of collapse them so you see a high level, and then you can expand it and go down. Oh, there's one a podcast with mike williams, who's a, a, some stuffed, some stuff i was thinking about in advance.
