Proposal: FF saved image buffers

I`, using FF with Affinity Photo, and there is a limitation for only one layer that can be brought to filter for making something useful. But this is really inconvenient, since many effect may require several maps. In my case there is a need to use same single "selection map" where color defines a zone in image with many layers for different effects. But there is simple solution.

Please, add and option to "store" current image into "internal library" under certain name. And then allow to "load" one of the stored image into color input easily. This internal library should be persistent between FF uses.

That way user would be able to open map needed for several effects first and store it under specific name. And then rerun FF with proper layers, loading presaved map from "internal library" in seconds
