FR: Audio Snap in Loop Construction Concept

I always feel  lack of "warping" capacity in Loop Construction and lack of "pitch envelope/shift" capacity in Audio Snap. These two concepts are great but there is no connection between each other in workflow. It doesn't make sense. I'm not a big fan of Ableton Live but it's sample editor idea is just amazing. Loop Construction concept is very suitable to be tool like sample editor.(I can  say nothing about programming difficulties). Yes, we can do everything what Ableton's Sample Editor did in Sonar but it takes more time and lots of "bouncing" process.  What do you think about it?
