Can you add bismuth which can grow colorful crytals if its melting and with a lower melting point than other metals and a bit radioactive.
what about a gear? which is a particle which instead of using electricity (glows), it changes color instead like copper-orange to a steely one. Basically a wire but mechanical.
another idea: multiply (mlpy),Wich doesn't act like clone,but instead of constantly making 1 element it generates one thats next to it (with all things like ctype etc) every half second. if a new element comes next to it it multiplys that element (with all c-type,temp,etc).
how about nnob? (nanobot) behaves like tron,but inside material's,and if you click on it with a stamp it will "save" that stamp and once it hits the materials the stamp is using it takes them and starts making the stamp. has the same colisions as proton's,moves like tron. it's probably way to much work for something like that tho,so I suggest to ad some additional functions,Wich I don't have any idea what they could be at the moment.
ALSO can you add powered portals
cesium 190 also knwon as strontium PLEASE
supraconductive element that conducts perefectly electricity at low temperature and can make metal powder levitate because of supraconductivity
add cobalt 59 and another cobalts to make the very radioactive bombs and reactors
soap worm that grows longer after encountering any form of virus
