Better support for multiple glossaries
You can use the glossary directive multiple times in a documentation without problems when you never define the same word twice.
This makes it possible to have a glossary with subtitles for topics eg.
I wonder if anyone ever had the need to put more than one glossary into the documentation. Maybe domain specific glossaries? One for math terms and one for chemical terms.
If this is a realistic usecase it would be nice to label the glossaries so that I can specify where a term belongs to. Maybe some kind of indicator as we use with the domains.
.. glossary:: math term (definition) This is a :math:term:`term`for my math specific glossary
