Can I disable languages from the General Config Settings? I started to develop my new Craft site in two languages (French &amp; German). Once done here, I have to put the website online temporarily in one of these two languages (French).

So I turned off all sections and entries to disable the language (German) but:


This was tedious and time consuming to do this manually via the CP
domain.com/de/ now redirects to the homepage with empty content instead of redirect to the 404 page


Questions :


Is there a faster and safer way to temporarily disable a website language with the General Config Settings?
Is it possible to disable some website languages depending on the environment and / or if devMode is enabled?
How about hiding the language switcher on the front-end?
