I suppose this is a bit of tech question, wrapped up in the productivity section ... As a big fan of the to-do list, I am also a little bit off-the-cuff when it comes to ideas. When something comes into my mind I tend to email myself using the subject line, rather than adding it to my list. I've got 3 email addresses, so this tends to work as I can compartmentalise my thoughts into the respective account. But I am wondering if there's a better solution - an App or something that you find useful and more streamlined for this kind of thing? TIA for your ideas.
