New filter fields: by languages

[SkyEmie]

Describe the feature or enhancement

Hi team,

I don't know if this is on the roadmap, but being able to filter via languages would be something really useful.

Use case example:
A person/company translates their website into a new language.
They might want to be able to observe the evolution over time, the arrival (or not) of new users using this language, by filtering on it.
This would give an idea of which pages they visit, from which countries, from which sites, how long they visit etc.

Regards, Emie
