Please please please can you let us edit the Alpha channel, make dodge and burn work, as well as curves. I'm a Lead Matte Painter in the Film and Tv VFX industry and i've seen the gradual decline of Photoshop over the years. Affinity is so close to becoming the main 2D workflow in Visual effects houses around the world, ilm, Framestore, Cinecite, etc etc. You guys and gals just need to sort this out. Until you do we will continue to use Photoshop which many of us dont want to do anymore, but can't make the change to Affinity unless we can edit in the Alpha channel. Its not just Matte Painters, its 3D artists, its game designers. we all need to edit the Alpha channel quickly and easily. Yet again i will have to save what im doing in Affinity and move it into Photoshop to finish off my shot
