I've coded that this evening for the fun and also because I'm using a todo list myself in a text file or in trello, but for very short term things (an hour or two, or three). Also, at my job, we recently made a folder to share crap files which is emptied each night. In the end, the post called "todon't" made me think about a todo list which fades and delete your notes for you.
I had reserved the domain name 'Notles' a long time ago.
Hope you will like that experiment. Please report bugs and dysfunctions, thx.
