Currently the species page shows precursor reactions. It would be also useful to display precursor species, similarly hidden at first and then displayed after a button press. It would also be a useful optimisation to only render the precursor reactions or species diagrams when the button to display them is pressed, as otherwise the MathJax rendering can add a noticeable slowdown for pages with lots of precursors.
