Right now, you can only filter generations by whether they have been published, background-removed, or upscaled. I have been upscaling my generations as an implicit way to "favourite" them, but now I have noticed that upscales have an expiry date.
Hence, in order not to lose my "favourited" generations, can we please just have a button to favourite an image (exactly like upscale), which is permanent and costs no credits, so we can filter that way?
