Show full query on result tab hover

If I execute several queries that only have a small difference near the end of the query, it's not possible to tell which tab corresponds to which query without counting (which is hard if you can't see all the tabs at once). If hovering over the tab showed the full query instead of truncating it to a certain width, that would be great.

Even better, if double clicking the tab selected that particular query in the editor (or put the cursor at the beginning of it... that would be very helpful.
