Default render export path & filename to the same filename and path as the background image.
Usually when working on a project you open the background image from a certain folder and want to save your render to that same folder. It would be a lot easier to have the default save path be the path that you opened your background image from and ideally maintain the same filename.
Thank you for the feedback! We do plan to enhance the way file path memory is shared between some areas.
This is how Photoshop works. Opening a file and going to save as, brings you to the same directory you opened the file from.
