This is really great! Two things that could do with improvement: - The backspace key quits the program. I've accidentally quit so many times after deleting my filter by holding the key down. - The filter seems quite quick at first, but when I add a period it slows down massively. ie. Search for "xorg", then "xorg.conf", the moment you type the period it hangs for a good few seconds, even though it's in the top level of my home folder. A breadth first search should find it trivially, so I'm assuming it's some quirk of the fuzzy matching.
