I agree with Wolfgang’s suggestions regarding the addition of framecommandhandler - I was going to suggest this thinking that the default line thickness might be too thin for printing.

But there are also some other features that could be added: e.g. a style parameter for the labels text so the font can be changed; and a vertical alignment (location=top|center|bottom).

And, although the StackExchange article originally linked used harpoons for the spin direction, other sources online use regular arrows so that might be an option to add?

Another detail - probably needs input from Jorge - at the moment if there is a single electron, the arrow is centred in the box. Would it help to have an option that up arrows align left and down arrows align right so that there is a space where the missing arrow would go?

(e.g. <https://chem.libretexts.org/Courses/Valley_City_State_University/Chem_115/Chapter_2%3A_Atomic_Structure/2.4_Electron_Configurations>)

So, all of that combined, suggests adding a defineelectrons and a setupelectrons as well?

I’d like to give it a go as a learning exercise - following Wolfgang’s module tutorial - but don’t want to step on anyone’s toes by taking over.
