I'd have to say an element such as francium. Granted, it will have the same effect as rubidium, but on an instantaneous basis, on a far, far larger scale. Other than that... some more gasses would be nice.

Non-element now, The ability to resize an existing space. many time have I tried to mix simulations only to find one is too big, and won't fit anywhere.

My mod has a few more gasses...

Nova
SGAS
just to name a few...

I think the solar panel one is a great idea as it will give an additional way to generate power and get more utility out of photons.

element 115: turns everything into bizr excluding the regular indestructable elements

i agree the solar panel should be useful

Except that currently, photons don't conduct electricity to anything, which is the whole idea of solar panels.
