Ardoise (blackboard) allows you to write/draw/erase everything (useful reminder). At launch (and at start of Windows) is displayed a transparent small version of your blackboard status "Hide mode" and in "Draw mode" you may use your blackboard like a real one, using chalks to draw/write and a sponge to erase! Includes a powerful automatic self-update mecanism when new versions are available.
