Remember Last Save Directory

This proposed feature seeks to improve Blender's usability by enabling it to recall the last-used directory for saving files, either on a per-blend file or per-scene basis. Presently, Blender lacks this functionality, resulting in potential inefficiencies and user frustration, particularly when managing multiple projects concurrently. This enhancement would significantly enhance user workflow and organization by automatically opening the last-used directory when saving render results, based on the most recent save directory within the current blend file or scene.
