SUMMARY GIMP has a set of tool options for controlling the preview image during a transformation: "Show image preview" and "Image opacity". These are useful options with no complete equivalent in Krita. STEPS TO REPRODUCE 1. Import two paint layers from images with no alpha channel 2. Add a Transform Mask to the top layer 3. Select the new Transform Mask 4. Activate the Transform tool 5. Attempt to align the two layers by scaling, rotating, and moving OBSERVED RESULT It is difficult to align the layers because there is only a little transparency. Even if the layer opacity is adjusted, the preview image still has ~90% opacity (when using a transform mask). Additionally, if trying to use a Transform Mask to scale a layer to the dimensions of something else, there is no way to disable the preview image and align the corners to a rectangle, a selection, or another layer. EXPECTED RESULT There is a tool option like in GIMP to make the transform preview less opaque, and an option to make the preview image invisible. Another option (though less flexible) would be for the opacity of the layer to be used for the preview while transforming a Transform Mask instead of the constant ~90%.
