After the beta period is over, firefly will be open for commercial use. We may use it for generating web design, app logos etc. For such tasks we might need the best result out of all the generated images. Since diffusion is a random process, once we click the refresh button the earlier image is lost. It's impractical to download a dozen images and later select best or open 10-12 tabs simultaneously. So I'm suggesting a compare feature similar to those found in shopping sites where we could place 5-10 images, pick out the best image and later remove the remaining images. This woud save a lot of time and could potentially be very useful.
