Mostly I want it just to make it easier to review the search results. Typically, I'll start a search and once I have a few hits, I'd like to stop the search (but keep the list of files up so I can pick one or several to look at) Many times I'll select a file by its size in order to minimize the chances of getting an incomplete file. The additional search results constantly change the search results list and it is difficult to remember which ones you have already mentally eliminated.
