I have a feature request to add On/Off toggle buttons for the extruder and heated bed. It's a bit of a pain having to type the temperatures and then type in '0' to turn them off. The button could change colours depending on whether it's on or off or maybe have an led type of indicator. When the button is clicked, it would turn green and send the m104 or m140 code with the temperature and when it's clicked again it would turn grey and send the m104 or m140 with 0. It would also be nice to have the actual temperature reading in a box close by because reading the scrolling temperatures in the communications window is also painful.
