Thanks. This is exactly what I was looking for! I didn't realize that a combobox can be attached to a model, and that a model can be filtered.
Imo multiple partial string match should be default behavior, which it is unfortunately not. E.g. inkscape only matches in the beginning of the string. Is there a GNOME guide line about this?
