Bravo to the developer who coded this. Earlier I was practicing some landscapes and had a few images opened on my desktop, all lined up horizontally at the top of my screen. However, there’s a few problems with this: 1) It clogs up my space: can’t see what’s beneath these images such as Krita’s toolbar and so on. 2) When moving/zooming the Canvas, these reference images stay there the same. 3) I’m on Mac, and these images won’t show up when working in Fullscreen mode. In Fullscreen, Krita takes over. And that’s when I said to myself, “This can’t be good. I need these references! What do I do?”
That’s when I decided to drag and drop them into Krita and imported as “Reference Image.” And that solves all the problems. Insert as regular layer doesn’t work. In order to have these images outside of the Canvas, you must “Insert as Reference Image.” You can rotate, scale, flip, or even lower the opacity of the reference image. Another reason to love Krita!
