Free PSD Viewer (Patreon)

So, while also doing some research on available alternative PSD viewers, especially for those that aren't so much artists or use something like GIMP where at least for the sake of looking, Photoshop's layers and such aren't available, I just stumbled on Photopea.com

It's effectively a free, browser version of Photoshop! I wouldn't count on it too hard to actually work in, 'course I could be entirely wrong, but it appears reasonably functional!
