Feature request: Automatic underscores for Greek letters

[Sinthoras7]

It would be useful if the automatic underscores also worked for Greek letters, such that when there is a \alpha and I type 1 not \alpha1 but \alpha_1 appears.

(This would be useful, but TBH if this is not easily doable, I would prioritize #30 over this, because this is just a feature, which would make this package more useful/better, the other one is a bug, which makes it unusable, for people, who are working a lot with siunitx/chemical environments.)

The thing is, we'd need a white/blacklist, because for things like \cdot if I write \cdot1 I definitely didn't mean \cdot_1. I have a WIP aas branch which makes a snippet data structure and lets you tag snippets, when/if I finish it we could look at the previous macro in the buffer, check if it's a snippet and if it has a "subcriptable" property and add subscripts with that. That adds considerable complexity though, I'm not sure it'd be worth it.

Yeah, I also think we'd need a whitelist/blacklist. I would probably just whitelist the Greek letters and wait, if there arise any issues, which would be solved by whitelisting more. Ideally, include a method, which users can use to add things to the whitelist

This snippet-data-structure would only work, if the Greek letter was also created by an aas-macro, wouldn't it?
Without directly checking, whether the expression before is element of the whitelist, it would be pretty tricky to expand it, no matter how it was inserted, I guess.

Right, yeah

A solution for users, who use the Unicode symbols, would be to create a variable, where the user can whitelist certain chars for the auto underscores.
Then, one could add the Unicode symbols for the Greek letters, f.e. 𝛼, 𝛽, 𝛾, 𝛿, etc..
