What features in DAWS (any of them) could you not live without? For me, it would have to be envelopes which control plugin settings on-the-fly. Nothing beats using a bunch of envelopes to control fine-tuning of a short delay and mix levels to create some interesting flanging/phasing effects. What about features you'd like to see? I for one would like the "Lock track" feature to show its face somewhere other than Samplitude. It's such a simple idea, yet it can potentially save a LOT of headache with the more CPU-hungry plugs, especially convolutions and reverbs.
