Hello, I am a big fan of your work and I think it would be interesting to add (in the #Isotopes tab of ptable) two things I am missing:
1- For each radioactive isotope, the daughter isotope(s) and probabilities associated to each decay mode.
2- Isomers. For example: the Ag110 is included in the table, but there is no data for Ag110m. The same goes for all other isomers.
