Access rights management for credentials should be presented in tree view with the structure based on group definition in Studio tab and Resource Management in System tab. Additional group view for security roles would be appreciated in System tab \ Security \ User Roles as well as the Access rights window (both for Access rights management and for group Access rights in Studio tab).
Currently, user roles in Access rights management are not even ordered, neither for Credentials, nor for groups in Studio tab.
This should enable to grant credential usage to single processes and whole groups of processes (eg all processes of department Accounting when defined as group in Studio).
