Keep in mind that there is a list of feature requests for Dune 3 like for example a new preset browser and favorites system. I've seen just as many if not more requests for that than for Microtuning so it's about priorities.
Also keep in mind that Synapse is only two programmers so unlike Native Instruments for example they don't have the manpower to add every little featurette that anyone can possibly think of.
So like I said it's about priorities. No telling what the future holds for Dune 3 so all you can do is make your feature request in a calm and convincing manner and hope it is added in a future update.
For the record my number one feature request will never be implemented so I've learned to love and enjoy Dune 3 for what it is today and that's one of the finest sounding synths I've ever owned or played and that includes both hardware and software.
