I am a chemistry professor who is finishing semester sequestered because of COVID-19. I bought a Huion 1060+ with the intent of using it write equations/formulas for my students in our online classes. I am not drawing major artwork – just an occasional simple molecular structure.
I know there’s an open-source extension to LATEX specifically for chemical formulae – I think it’s called chemfig – here’s what I just found on quick lookup:
