My favorite art program supports dragging images straight into the canvas to open as a new canvas, or into the layers to add as a new layer. It can take .webp in the canvas and open it just fine, but try to directly insert it as a layer does nothing. So I gotta open as a new work, Ctrl+A Ctrl+X, Ctrl+Shift+Tab, Ctrl+V just to put a webp as a new layer. And of course it can't even export as a webp either.
