An X11 desktop background time manager.
Zoom in/out with the scroll bar down to 5 minute precision.
You can add/remove rows arbitrarily. alt + click - toggle the color of a task. ctrl+drag - adjust a cell + cells to the right of it in time.
Easy custom themes.
Writing your 405th plan? Struggling to adhere to it?
