Symbol Package similar like the abbr Package?

In my document project, we have a list of symbols used.
At the moment, this is solved somewhat arkward and I would like to improve it.

I am already using the abbr package for a list of abbreviations. Essentially, I would like to have something very similar for the list of symbols.
Especially the feature of that only the mentioned abbreviations are actually listed in the outline would be nice for the Symbol list as well.

However, I don’t see that I am as gifted to fully understand the code of abbr, so that I would be able to create a SymbolList fork of that abbr package.

Does anyone see if that is feasible at all and is anyone else interested in that package (who might help to implement this)?

Maybe it’s clear to others but I’m not quite understanding what the symbols will be. I guess you want similar functionality to abbr, but in parallel to it since your symbols are not abbreviations.

Looking around Typst Universe I found amlos – Typst Universe which might provide what you need.

Sorry for not explaining it clear enough.

Yes, I also had a look at amlos. But there, you need to define your symbols directly in the text. That way, they will be clattered around your whole document.
The syntax looks similar like with footnotes.

In abbr, you define your abbreviations in a separate place and you can use them using the @ reference operator throughout your whole document. Plus, when you print your list, only the referenced abbreviations will be printed. This would be handy for Symbols as well.

I would imagine something very similar like abbr, but for storing a small dictionary with the symbol’s name, Unit and description (and maybe other information, as in amlos).
Have not tested it, but I assume abbr is currently not able to store this instead of text.
