Create private (password protected) collections

Perhaps you want to have a collection of images which only a client can see?  Now you can.  

Create a password protected Category and add collections to it.   Only users with the password will be able to view those collections.  

It is even possible to lock your entire site by locking the first category and dragging it to the top.  Just don't do that on accident.

See the video for an example and instructions.  This feature is in testing, so let me know if you have any problems.
