Michael, please feel free to add an example for resetting folder labels.

Your last sentence already makes it clear. This could only be an 
addition to the current hooks but never be required as a replacement 
for the prefs callbacks.

What about general preference change hooks? We trigger some changes 
when the theme is changed, for example; why not moving all of the code 
that runs when a pref is changed into a configurable hook. Yes, people 
would have to enable the default hooks, but that gives them 
flexibility also.

I still don't see this as a huge problem since the correct labels will 
be used after the next login. But if this of great importance for you, 
I suggest that you use an API method instead because we don't have to 
load each and every application's lib/prefs.php then.

No functionality broken - this is a UI thing only.  But it is kind of 
annoying and looks unprofessional.  I guess the other option would be 
to force a logout/login instead.

I guess we could live with that, or is there any functionality broken 
when that happens?

If the language is switched during a session, the prefs code should 
check for a callback function (i.e. prefs_language_switch) in all app 
prefs.php files.



Example - user default is language A.  User logs in to IMP.  Virtual 
folder labels  are in language A.  User switches to language B.   
Virtual folder labels are not updated.
