i actually have suggestions for more than one area.
1) as far as hardware intergration i would suggest adding mappings for as many keyboard controllers as possible. for instance i use an M-audio oxygen 61 keyboard. i cant use the transport and other functions without making a midi learn instrument. there are mappings for axiom and even oxygen 8 but not the other ones.
2) features for production would be stuff like pitch shifting, envelope shaper, transient designer, wave distortions options as well as other distortion options such as the way cubase has it now
3) for ampire need a gate pedal. options such as a looper, amp and tone matching. i could list a whole lot of other pedals that's needed like a synth pedal, doubler,, other options for distortion... also options to blend amps such as in Bias FX. just look at all the pedals mentioned in the Axe FX. maybe options to change tubes, bias and other options like Bias FX and Axe Fx.. More cabs, more amps.
4) plugins multiband exciter, master bus compressor, linear phase EQ.
5) editing process would probably be aligning transients without a plugin. such as aligning vocals and instruments (guitar, bass, drums)
6) for recording maybe adding on the inputs a "pad" feature so people who have interfaces that dont have the pad function can use it. also maybe adding something that models a preamp with EQ and distortion options. and have it optional whether people want to use it or not. some might some might use their own. .
7) mastering-think izotope ozone
