I figured out a an Idea for us lowly folk to understand what the advanced users do to make their saves that much easier to understand. A new addition called MOUS. Called Mouse, this new addition allows you to click on anything in the game. It basically gives you a pop up that tells you the tmp, tmp2, temp, ctype, and anythiing else corresponding to what you clicked on. Even tells you the element name should the element not be part of the side-bar options.
You can always use the debug HUD and/or a HUD extension. That way you won't even have to click, hovering over a particle is enough. There's a HUD extension on the scriptserver, although I haven't tested it myself.
I have an outdated mod for that https://powdertoy.co.uk/Discussions/Thread/View.html?Thread=20255 :D
