As in title; I don't know what the default values are so I don't know what values (if any) I may have accidentally changed. I believe hiding the "reset to default" button when the value is already default is the usual way of indicating this.
The GUI currently in use is deprecated and will no longer be developed; in the unstable branch I have removed these windows/widgets and the FLTK dependency altogether in favor of a ground-up rework using ImGUI.
