From the github page: "Once in TextMate mode, completion is done against the entire directory tree at once, using partial matches." Can't you do the same thing

From the github page: "Once in TextMate mode, completion is done against the entire directory tree at once, using partial matches." Can't you do the same thing with fuzzy finder using /filenamepart ? And doing this in the regular fuzzy finder in a relatively big directory tree, does take some time unfortunately :/
