I think that antimatter would be helpful and interesting, it should explode on contact with any other particle and produce allot of heat and pressure.

I think pencilply has noted that antimatter will be in the next release of TPTE.

Could there be the possiblity of proper gravity, so when you put a liquid in a bowl like structure with another element seperating it but still leaving a gap at the bottom for the liquid to run to the other side, and then level out with the other side. Or at least have a switch/button that turns on the true gravity?

I'd like to see Thorium and Neptunium for use in reactors, and Some isotopes of Hydrogen, like Deuterium and Tritium.

different physics for a different physics engine (grid based isn't too good for that type of simulation, true particle-point simulations (not in grid form) are)

v38 is great. Seriously. But electrodes are pretty much useless, due to "melt everything on screen" behavior and instability of plasma. Maybe make them create arcs of thunder instead?

But thunder is essentially plasma lava (with a few effects). What an arc needs to be is ARC - a new element that is like an airborne spark, but I think that capacitance and air resistance should be taken into account. For example, two electrodes 10px apart only need one spark to arc, but 20px apart should require 2 or 3, etc., etc.
