Vertically aligned dynamics and textscripts

All DynamicLineSpanner objects (hairpins and dynamic texts) are placed with their reference line at least 'staff-padding from the staff, unless other notation forces them to be farther. Setting 'staff-padding to a sufficiently large value aligns the dynamics.

The same idea, together with \textLengthOn, is used to align the text scripts along their baseline.
