gtkbfc is a program that replaces the standard Gtk+ file chooser in bash scripts. It provides more features and improvements.
Keep in mind that gtkbfc is not a perfect solution and may not work with all programs. However, it has been tested and proven to work well with programs such as gimp, firefox, and gedit. In order to use gtkbfc, you'll need to make sure that you have GNU Bash and rxvt-unicode installed.
The latest version of gtkbfc includes bug fixes, specifically addressing a minor issue with unquoting filenames entered with the supplied helper. Overall, if you're looking to improve your file chooser experience and are comfortable with a bit of hacking, gtkbfc might be worth checking out.
