Not just adapt their size to the amount of text in them, but actually be able to make a note bigger along with the text size, so you can have some things stand out more than others.

Hello! I do agree that this would be useful, but I'll have to think about it, as none of the Tasks are currently built to be scalable (except for the Image Task). Doing this would require some pretty deep underlying changes to facilitate (basically drawing Tasks not to the screen, but to something else that is then drawn to the screen, so that they can be stretched at will).
