Brush smoothing (fidelity) per brush preset
Currently brush smoothing is set only by double clicking the brush tool icon and is universal.
Logically it should be set at the brush options dialogue, individual for each brush preset along with angle, size, roundness etc.
Each brush reacts differently, and there should be an option to have brushes with various smoothing settings all available at once.
Saving brush presets would retain their smoothing setting as well.
Ideally, Illustrator should adopt some of Photoshop's brush engine settings.
