Hookmark's use of DEVONthink's automation to get deep links to PDFs

That was the code for the Get Address tab. The Get Name tab reads:

tell application id "DNtp"
    if exists (content record of current tab of window 1) then
        -- current open item
        return name of (content record of current tab of window 1)
    end if
    
    if class of window 1 is equal to viewer window then
        set selected_items to selection of window 1
        if (count of selected_items) = 1 then
            -- current selected item
            return name of item 1 in selected_items
        end if
    end if
    
    -- selected group
    return name of root of window 1
end tell

Could that be simplified in similar fashion?
Hookmark and DT3 do work very well together.
