Photopea is really good. It pretty much has all the tools i ever need as someone who had a passion for graphics design/photo editing in their youth but never went pro. It gets shit done for some simple stuff i want to slap together now and then.

But some stuff gets laggy really fast. Like worse than PS CS2 on my Pentium 4 shitbox 20 years ago. I wish we could have Photopea without browser technology in an appimage/flatpak or whatever. It would be perfect.
