Hello Aline, I refer to the latest version of the User Interface Design Specification - Kimchi, 2014-12-23 (aka UI Design Spec) which defines the following structure of functionalities: *Host* (second level navigation via panel areas) Performance (System Statistics) Basic Information Repositories Debug Report Software Updates *Guests* no second level functionalities *Templates* no second level functionalities *Storage* no second level functionalities *Networks* no second level functionalities *Administration* (second level navigation via collapse/expand) Firmware Update SEP Configuration Power Options Configuration Backup Network Configuration SAN Adapters Sensor Monitor *Problem Statement* We already decided to move all Administration functionalities to Host (currently not updated in the UI Design Spec). We are currently facing the following problems: 1) Host now contains 12 second level functionalities, all other (Guests, Templates, ...) none. We need to introduce a second level navigation for Host other than collapse/expand 2) The navigation bar elements Storage and Network (refering to Virtualization) also exist in the Host context. This might confuse the user. *Proposal* The described problems can be solved with the following changes: 1) Introducing a second level navigation 2) Changing the structure of functionalities as follows: *Host* Performance (System Statistics) Basic Information Repositories Debug Report Software Updates Firmware Update SEP Configuration Power Options Configuration Backup Network Configuration SAN Adapters Sensor Monitor *Virtualization* Guests Templates Storage Networks *Containers (future extension)* to be defined Let's start a discussion on this. Kind regards Jan
