We need a few more elements in the gasses and radioactive sections of PT but not stupid ideas like a gas that glows green if it touches water becuase it would look pretty or because you really need a stupid elemnt to finish off one project of yours and will never need it again.
I think that concrete should harden several seconds after spawning, it has always confused me as to why its a powder (in the PT).
Just another thought, isn't the name 'noble gas' just a little generic? The purplely-blue colour of the plasma is very similar to the discharge colour of Xenon. I know I'm being picky, with the name and such, but I still think XNON would be a more appropriate title for the coming element.
edit- BTW, can we get an ETA on version (39.0?) please?
Also I don't know if this falls under the elements category but can you PLEASE bring back the alt/control/right click thing?
You know like how there is a red square on one element and a blue one on another and on my mac I made the erase element with a blue a square so everytime I needed to erase something I would just hold alt (on my mac) and it would erase it really easily now everytime I hold alt to erase something (or whatever particle the blue square is on) it doesn't work it just samples whatever particle I click on.
Although it doesn't work when I use things like shift and ctrl or both when I want to delete a fill section or in a line etc, and it works when I right click somewhere but that's not as natural, PLEASE bring it back use another button to sample particles PLEASE PLEASE PLEASE!
