Todo lists
tome: I keep my TODO list in a single text file.  I have a key bound in my window manager to open it in an editor, and ask me whether to record changes to version control when I close the editor.The formal is very informal and ad hoc.  You can see it here:http://pastebin.com/f53965a01I also have an hourly cron jobs that extracts the tasks under "TODAY" and mails them to me.
