    Special case root for search, part 1.
    
    The root path does not have a "local search" functionality, as
    that would be similar to the "global search" and so, confusing
    as hell. Instead, use an "Open path entry" functionality for a
    better discoverability of this function (part 1), and make the
    search buttons open for there the search entry empty (part 2).
