Hi there.
A preview option could be great (may be in a lower quality process) to be able to listen the horizontal and vertical margins and strength parameters on the fly.
I think cast and mold options are underrated and I even find the cast option a super tools to solve masking problems using it together with other tools (eq, multiband compressors, etc) but it should be great to use cast tools in real-time to be able to listen the real interaction between selected tracks or layers into the project or mix session.ù
Any beauty feedback will be wilkommen.
Kind regards.
Gustavo.
