Separate render result from other images (skins, material etc.)

Want suggest to Separate render result from other images (skins, material etc.) eg. additional list of images that was renderd, with history of these images (something like cache of renders if render was restarted) to compare or something (other operations on Shader/Nodes). Sometimes is hard to find the render file..

• the render results should be good recognized by layer (if more than one then render is runing many times)
• can be filter for types or limited model of dock like outliner for the files
• Search improvement for render result
• Sequences images as render results lists in animation
