Moving the canvas previews is great. It would be nice if it were possible to scale them as well.

When you work with LED screens, often your biggest and most important screen is also the one with the lowest resolution. In Millumin, its canvas can be then smaller than the canvas of the preview monitors or the canvas of other, less important screens. It would be great to be able to reduce their size, for example to 1/2, 1/4, or 1/8 of the original size. Then the less important canvases would take up less space and make it easier to focus on the most important canvas.
