Inspiration seldom arrives neatly organized at a convenient time of day. And, face it, if you were that organized you would carry a pen. And a notepad. So just type your ideas in as they arrive, and organize them later!
Take your lists anywhere. As many as you need. Organize them as you like, or just sort them alphabetically. See outstanding items on your Start Screen. Once they are done, check them off and clean up with a click. No ads. Just lists.
