The current interface is split in multiple places from where an account can be managed. This is quite cumbersome for new users and especially for non tech users.

Current layout for managing an account:
    - Separate location with all the identities
    - Separate location with all the incoming server
    - Separate location with all the outgoing server
    - Separate location with the contacts
    - Separate location with the calendar
    - Separate location with the tasks

For adding an account there's a wizard that helps with that, which in the case of Kolab Groupware it adds all of the above.
For other types you'd have to add each one separately.

If by any reason there's a need to remove an account or perform certain changes (the server URL has changed) this is incredibly tedious to do, because a user would have to remove/modify each one of those separately, this way providing much confusion amongst users.

As an example, Thunderbird groups accounts and each account has a submenu with all of it's settings (identity, incoming and outgoing). We could go one step further and provide full account control from one place, especially for Groupware servers. In the meantime, not removing the possibility to add separate account for each one of those. Maybe even allow multiple resources to one account.

Currently our layout is focused on separate resources. My proposition is that we group those resources to accounts, to ease their modification and removal.
