I wish to change this popup for every program calling
public class OpenFileDialog : FileChooserDialog {
Ideally it would involve removing desktop and changing search etc. I was just hoping somebody knew where the underlying files are?
The UI layout for the file chooser dialog is in gtk/gtkfilechooserwidget.c
