this is rather minor, but inconsistencies bug me a bit

• go to host items - the link to go back to host list is "All hosts"
• go to a screen - the link to back to the screen list is "All screens"
• go to item prototype list - the link back to the lld rule list is "Discovery list"

it would be better to have the same style in these places.
"Host list / Screen list / Discovery list" (and so on for maps, slideshows...) would be preferred - especially in the case of hosts, clicking "All hosts" in most cases wouldn't even give all hosts.
