Despite this not being FOSS like GIMP, I think it's great that there is at least some very viable alternative that can run on Linux even with some workaround, for free (besides Photopea).
I enjoyed it more than Krita. I find the UI more intuitive and closer to Photoshop, which was my #1 (at least for CS6). Photoshop remains the only piece of software that doesn't have a reasonable subsitiute or Linux client.
