One thing that drives me nuts every time I save a new file or 'save as'. File chooser appears and I automatically start typing to enter/change the filename. But the filter input always gets focus and now I'm filtering the list of visible files instead of naming my file...

(Yes, I know I could try to submit a PR but I don't have the energy to figure out the Gnome governance process.)

plus the filter search is very slow. plus the async race conditions if you click or keyboard enter too quickly.
