Sorry to barge in into the thread, but regarding the isotopes with current pop-out style: As a person who lately started collaborating with NMR people I think it will be nice if one can filter them by half-life/abundance (e.g. to filter out anything that has natural abundance of 0 or below x), and then look at magnetic/quadrupole moment to see if resonance people can measure it).

But anyways, thanks for all the work you've done! I've been using it daily for the past 10-11 years, it is a great resource :D

I didn’t mean isotopes. I want to challenge you with this: https://en.m.wikipedia.org/wiki/Table_of_nuclides but I misremember the name sometimes.

I forget you added that sometimes, but I did love finding it! What I am missing is the experience of looking at that curve/smear of a graph that is the table of the isotopes.

Keep up the good work, probably sums it up best :)
