It would be really useful if when you save a song structure it saved extra information. Example: 1/2 tempo and full tempo (if changed) and also the power hand information for each block. Having this saved would make it so much easier to make simple arrangements much quicker. You could find a nice loop and throw it in the arrange using a structure and have half the work done. It only really works for now with pop verse chorus verse type music. Having this extra info saved would make it really good for Black/Death metal.
Does SD3 have any equivalent feature?
