Draft: nautilus-properties: replace GtkFileChooserDialog
As it is not possible to add widgets to the header bar using the GtkFileDialog class, I implemented a reset button as shown in the images below.
I don't know if that way would be the ideal project. But it was a solution I found.
I marked the MR as a draft because I would like to know what the developers and design team think about it. Anyway, it served as a lesson.
Thanks!
