Lets say I have a customer with read-only rights, and that customer only needs to see one device or sensor. Imagine that, this device/sensor is somewhere in my group trees 4th sub-level, like Probe->Administration->Servers->Clients->ClientA. Now when I give my customer reading rights to that device/sensor, he sees the whole way to there. He can't see other devices and sensors in those sub-levels, but the long tree sub-level steps are visible. Main problem would be that, at some point there could be information only for inside use, so it would be nice if users who have access only to a specific devices/sensors and not the whole tree, that only those devices/sensors would be visible and not the whole tree.
