Oh no, I meant a clone stamp tool just for rasterized layers. I do thumbnails for a youtuber and I prefer working in Affinity Designer over Photo a lot more because of the vector based tools that arent available in Photo. But I also use screenshots and mask out parts of it or use the screenshot as a background. But sometimes theres things I dont want in the background and I love the clone stamp tool for that, but I would have to move it all into Affinity Photo to do that and its a HUGE pain since it takes so long to load.
I really just want to use the clone stamp tool in Affinity Designer on a single rasterized layer, it doesnt need to use any of the vector graphics
