1) It would be nice to support F4 key in the same way F3 is supported. It is really common case (for me of course) to feed whole results into panel just to edit single file. It is not convinient since this panel needs to be manually closed after all
2) option to disable automatical resorting of newly found files during lengthy search. It is annoying to see that the file you need is jumping out of view because of resorting. The common case (for me again, of course) is to find single file using little data about it`s content and this resorting really slows things down
