Ability to warp, transform, distort an image or parts of an image with precision

When I collapse one or more layers with certain merge modes (such as softlight), I sometimes end up with a different result. I'd like to see it fixed so that what I see before collapsing layers is exactly what I get after collapsing layer.

I'd like to see layer masks improved, so I can do things like move or copy them between layers and link or unlink their movement with the parent layer. I'd also like to see improved brush compatibility and be able to apply effects and adjustments ...

Currently transforming a texture takes multiple clicks - one to scale, one to rotate, one to skew. and if you want to flip you have to apply the transform then flip, the restart the transform Very clunky. It would be nice to have one tool which co...
