Workflow assign user to handle node in given state I am using Workflow module to implement moderation policy in one of my project. It is working fine. 
But I want is when a user changes workflow state of user, he must be able to select a given user also from given user group, who will be responsible to manage the node in that state.

So, ideally it would be drop-down of user, form where admin can select user to whom the the node be assigned. 

I searched a lot, but didn't find any solution yet. Is there any way to achieve this.

-- Many thanks for your time.
I am developing a module that address that very issue and some other things. Besides it is on sandbox yet, it is fully usable (I am using it on production).


  Workflow Hide Fields is an addon to the Workflow module.

git clone --branch 7.x-1.x git://git.drupal.org/sandbox/fpap/2575131.git
