Thanks for the feedback, I'm glad you like it!
1. Have you tried turning up the crossfade slider? This might make it sound a bit less harsh. I'm not sure a bend transition from the punch to the tail will ever happen, because it's a lot less efficient on the CPU to do that, and additionally it's not supported on at least 1 of the algorithms.
2. Not entirely sure what you mean here, I think you're talking about the ability to shift the tail part a bit? That's a good idea, and actually part of what I have planned for an upcoming feature already.
