I just had to filter a lot of my dumb stable diffusion creations, and I discovered that while I can, for example, filter by favorites, I cannot filter by non-favorites. I was tagging the ones I wanted to keep and not the ones I wanted to delete, and I had to use stars in the end to be able to do this.
Is an Idea... for all filters... color/no color. Fav/NotFav. Picked/Rejected/No Flag.
I'm loving Peakto, since it has allowed me to find and process my catalogs in a way that LRC has not been able to do, so I'm still expectant of what you will come up with on Peakto.
