Allow editor choose language for UI independently of the content language

[agitator]

It would be useful for editors to set the language of the UI independently of the content language.
For standard content it's not so much of a problem, but try to configure a collection in a language you don't fully understand.

What would be necessary to achieve this?

There is an addon that does exactly this:

It patches the language negotiator to check if an editor is logged in, and if so to force the language previously configured on the control panel

@erral thanx, will check it!
