Makes sense, we should try to make this one platform independent. I 
guess we are not there yet, but we should plan for.

Keeping wok featurelss makes lot of sense. I guess what we need to think 
about is the scope of user and roles management. From what I currently 
see there are currently 3 roles/profiles defined: Administrator, Kimchi 
User and Virt User.  With the agreed feature split User Management is 
available only if Ginger is installed, which is true with the current 
stable implementation as well. Since in the current implementation 
Kimchi is always available we don't have an issue offering Kimchi and 
Virt User profiles by default, but after the separation these profiles 
make sense only if Kimchi plugin is installed. Theoretically any new 
plugin could bring in the requirement of new profiles.
The other question we have to clarify is:  do we need User Management 
when Ginger is not available as plugin ?
 From the implementation I understand that we are talking here only 
about locally (on this host) defined users and roles, ldap user 
management isn't performed. From this point of view it's fitting in the 
scope of Host Management. The part not really fitting is the plugin 
specific profile aspect.
Since we want to keep the plugins as independent as possible from each 
other, one option I see is: if a certain plugin has the requirement for 
a certain user role it has to expose the description of this role in a 
tbd. format to the User Management feature.

We are working on that one.  If it proofs to be too much of work or 
uggly hack, I would propose to leave it how it is for now in the old 
UI-design (meaning keep Administration tab)  and do the final 
UI-restructuring based on the new UI-Design.
