Pressure curves - pencil and vector brush - linear/points and curve based (and potentially having to customise each individual brush)

[Secret Goldfish]

It would be great if the pressure-curves/width-settings graph/profile for strokes was based on curves rather than linear points when using the pressure controller (and a tablet).

Adding/creating a pressure curve profile to strokes (after being drawn with no pressure controller set) has this non-linear/curve-based feature but using the pressure controller (and a tablet) translates/interprets this pressure information as linear points instead, which can create odd and less natural results than being curve-based (when linear/point-based instead).

Being able to add pressure curves to vector brushes later (if you didn't originally use the pressure controller) would be a great addition too, The pressure curves currently display in the pressure graph/profile but do nothing UNTIL you adjust the individual brush settings, which can be confusing and convoluted (I currently create duplicate/copied versions of my brushes with internal pressure/width adjustments/settings). 

......the addition of the new 'keep selected' feature (in the pencil tool) being added to the vector brushes too would also be good..
