1) Composer Chord Tool - Think Toontrack EZKeys within Sonar - but with a bigger chord display up top
2) Improved efficiency - i.e. the ability to run more effects/tracks/instruments with the same Processor and RAM spec
3) Stability across Each unforseen Windows update
4) Control Surfaces - seems like Sonar never seems to have out of the box integration with other manufactures' products
5) More Pro-Level Prochannel effects (some of them need an update in quality, some effects just don't exist in that format)
+ 6) Artificial Intelligence integration, the track assist type of features in Izotope Products are great for starting points or getting ideas - if those kinds of tools could be integrated into the DAWs tool sets (LP EQ, LP Comp, Limiter, etc) analyzing within and across tracks, it could be a game changer for the beginner to intermediate DAW user. However, I know getting to Izotope's level or better would be a major feat. Just wishful thinking. I've said before I'm not a fan of LANDAR, but the quality of Izotope's AI and tool set is a different animal, not to mention the ability to full tweak after the AI makes changes.
