[Request] Better integration with Thunar (sorting/selecting)
Both Ristretto and Thunar are components of the standard XFCE desktop environment, but they seem to lack much needed integration. This seems to be at least vaguely a project goal as Ristretto already has wallpaper setting integration. As of right now, Ristretto does not respect Thunar's sorting orders and there is no quick way to access a viewed image within Thunar. Ristretto should be able to obtain the current directory's sort order (as set by thunar) and follow that when an image is opened (this should be another option to the already existing sort order options so people using for example the terminal can sort through ristretto itself). Ristretto should also be able to show the currently open image in thunar (or any other file manager if the interface for doing so is generic), either through the file menu or from the rightclick menu with a "Show in file manager" button.
