At the end of the day all you need to manage your life is a single text file – and "_ MyTextFile [mytextfile.com/] will give you no more and no less.
MyTextFile is a minimalistic online text editor for a single plain text file. If you want to go fancy you can chance the typeface/font size or the color scheme. MyTextFile also has built-in revision control and will autosave your document every five minutes. And that’s about it. I love it.
