Change language code

It’d be usefull to have the option to change the language code for example from LL to LL_RR
My use case: A translator created a new language (great!) under the category ‘fr’.
The software is desigend to take ‘fr_FR’. Now I would need to change the code. If I can’t I always have to rename the folder after download.
Or would be advisable to create a new LL_RR and copy the existing LL to it? Would that be even possible?

Hello and welcome,

our backend is already able to do it, so we can perform such a change for you.

@janbilek : Do you have any estimation for this feature?
