I think it would be cool if in the game there was a feature that you could turn on and off that would let you view the different interactions that an element can have with other elements when you hover over it's icon in the bar.

So for example NITR + CLST = TNT, so both NITR and CLST would have that interaction shown when you hover over the element in the bar. I really feel like this would be a very good feature, because it would boost the creativity of players and what they create, since most people aren't aware of all the intricate reactions in the game. I do know this data is listed on the wiki, but the more convienient something is, the more players will want to explore that.

But then of course, i do realize that it probably won't be added because it's a huge pain to implement something like that.
