Depending on the context of use of LimeSurvey, to guarantee more security for its operation (Companies, State Organization, Associations, Individuals, etc.), it is sometimes necessary to block certain very useful functions, but which could not be adapted to the context (ex: Sensitive site: no external file)

More generally, certain options as superadmin to "block" some functions to avoid bad manipulation by questionnaire managers.

An example of functions:
block the possibility of depositing files (the File question) ==> (Ok using the questionnaire menu settings - we can hide the question.)
Block the use of the image, video, network modules in KcFinder, except for a group of users.

Also to add:
A user group management, with a supervisor.
We could give the supervisor the right on the files for example, or to an entire group. Currently this is not possible.

And also to think about "mass" operations on users (eg: management of expiration dates (previous request).
