Do you use Photoshop? The underlying engine which gives support for layers and smart objects is in itself such an amazing piece of tech that nobody seems to get even close to (and I’ve tried them all). The brush engine is fantastic, liquify and the general support for plugins, and heck, just the basic math behind the filters.

Canva and Figma are layout tools, not for pixel editing.

Recreating it would make it faster and cheaper, something that has been driving software for decades.
