Mine is more metering options (to get all the channel meters to be able to behave like VU meters with -18 dbfs as 0db).
And a project information text export.
(P.S.: I know you can futz with the meter appearance via preferences but it wold be nice if it could match the options of Logic)
I would have liked to see a better/simpler way of layering synths; I am jealous of FL Studios layering (with the parent/children thing). Simple, quick, layer as many synths as you like.
Also, something like Ableton macros; where I can assign multiple parameters to one knob of a control surface.
Other than Cubase is just fine for me.
