The CC lane improvements are good but I'd like fewer points on the curves when drawing them in if possible.
I believe there is a PPQ (points per quarter?) setting that lets you determine the default resolution of drawn CC. With the old bars, setting this low would give you choppy CC lines, but perhaps now, if you set the default curve to something other than square, it'd do what you're describing.
I believe this setting can be found under the "MIDI" tab in preferences.
