Request - Filter keypress delay

Would it be possible to add a keypress delay on the filter box so it waits until you finish typing the filter?

Or maybe an option to filter on press of Enter key instead of immediately on every key stroke?

Its just that when I have a large number of files (>20k) each keypress in the filter box results in a wait of a few seconds while the list is filtered on the incomplete filter, which is rather annoying.

thanks Florian.
