I think that it would be cool if there was a menu of every thing that burned but cold, such as cold wood that did not react to fire the same way normal fire doesent react to cflm. and would burn with cflm. honestly I can not think of any uses for it but I have seen people make thing out of elements I couldent think of in a lifetime.
yeah, a good straight answer.
What would be the use then? If you can't give us any, then it's not going to become real.
"honestly I can not think of any uses"
That is the keyword. Adding <useless feature> to <insert software here> has almost universally resulted in extra bloat and complexity that has almost always been a Bad Thing™.
It's like suggesting that windows add a small pink blob that randomly falls onto the screen and moves around before leaving for a few hours. Useless, but they add it just because why not?
maybe just add some cold elements. Elements that impode.
