Can you add the ability to place free text? This is a very slick little tool. It would really benefit from some options concerning how to change state. Perhaps a menu that allows you to select which states are allowed, i.e. just high or low and no unknown. Or perhaps a toggle state that make everything after the point of click the new state rather than adding an area of different states. Overall this is a great tool and with just a few more features could really be a great simple alternative to the more complicated timing diagram tools.
Thanks
Totally agree
