Add a pressure slider alongside temperature slider
I don't even know if this is feasible, given the amount of information this adds and how it would work with the programming, but I think it would be a nice addition to Ptable and may solve some issues I've noticed with the melting and boiling points.
E.g.: tungsten is said to have the highest melting point of all elements, but the table shows carbon melting after tungsten. Also, carbon's Wikipedia page says it sublimates at atmospheric pressure, so it shouldn't be melting at all.
Thank you for your attention.
