Hi, I have an idea to make signs which display current preasure and/or temperature (example if you write 123x45P in sign then you watch preasure on coordinates 123x45 (coordinates in pixels))
XxYq (X-coordinate x, Y-coordinate y, q-P/T (Write P if you want preasure or write T if you want temperature)
When you open sign window you can see coordinates of mouse pointer in corner.
The info line, containing pressure, temperature of the cursor pixel would be much easier to read, if the length wouldn't change all the time. As we know the maximum and minimum length of the strings (heat and pressure, that is), it would be great to fill up with leading zeroes or space characters.
