Well, it's more the background/layout style I guess. All the action buttons
(up/down/delete) should be grouped together in the same column with the
same background colour. For consistency of layout I guess we may need to
always show all buttons, but disable up for the top row and down for the
bottom row.

Yeah - what we normally refer to as the API tests (as that's what they
primarily exercise). I'd look at storing a setting of the new type, then
retrieving it and ensuring it comes back as expected.
