I have been playing (seriously) for a couple of months and I tell you I am still finding features.
The 2018 version incorporated all the suggestions that I had made to Mixvibes and then some.
I am finding couple of things that I like to have and they either have it for next release or can be easily implemented via basic scripts.
I don't think Cross PC/MAC can be saved at this point. Not even If another version would come out in the next 6 months because they are too far behind.
