All of these are Editor related Suggestions.
IMHO the search box retrieves and shows way to few results. There seems to be a maximum of 16 items when doing a search. Would it be possible to increase this? Maybe to a custom level => infinite?
Also, would it be possible to split the Search box and the Hierarchy panel? Sometimes we need to find a parent item based on the child items name. I know this request is probably more complicated than the first.
Also, would it be possible to search for items with a specific Tag?
