The goal of the panel is to offer a central place to get information about plugged in iDevices (iPhones, iPod Touches, iPads), and manage them.
iTunes is the only application offering similar functionality to what we are trying to achieve.
The panel is separate in 2, left hand-side is a treeview representing the device, and a number of actions/items related to its management. The right hand-side is the management page itself.
This is currently mostly implemented in nautilus-ideviceinfo (available in GNOME git). It will display information about the device, and allow minimal changes.
This page would be implemented using features from sbmanager and ideviceinstaller.
