The bad news is that opaque is still the default, so you have to take time to adjust the opacity mode each and every time you restart GIMP.
Thus, if you want to transform the layer in relation to what's under it, you have to follow these steps: 1.Start the transform (scale, rotate, unified transform, etc.) 2.Hide the current layer. 3.Adjust the opacity of the transformation preview in the transform tool options. 4.Set grid to zero lines 5.complete transformation 6.Un-hide layer to see the results. Additionally, you have to do this for each tool you want to use for transforming at least once per gimp session. This is a lot of work, when all you want to do is see what's under your transformation while transforming. The steps could be reduced dramatically by changing some of gimps defaults: 1.Start the transformation (GIMP automatically sets transforming layer display to hidden. This is necessary to see the result of your transformation in can see relation to what's below it. GIMP could also set the transform visibility to 75% opacity by default, giving an even better view of what the transformation is covering up. GIMP should hide grid lines by default during transformation unless the user asks for them. They have only ever really gotten in the way, and I have yet to find any good use for them.) 2.Complete the transformation (GIMP unhides the layer, thus showing the transformation in its complete state at full opacity) So as you can see, this would cut down the work the user has to do a lot when transforming. It would also bring GIMP's transforming into the same ease of use as every other graphics program I've ever used professionally. :) After having lived with it like this every working day for the last 6 years, I have to say, it's still one of my biggest gripes about GIMP's GUI. Can we fix it? Please? Pretty pretty please? :) -C On Sat, Mar 4, 2017 at 4:26 PM, Peter O'Regan <peterore...@gmail.com> wrote: > I see what you describe in 2.8 and I agree it would be useful.
