It would be really nice if characters could inherit attributes and macros from a parent. That way I could define a base set of attributes and macros which everything has (hitpoints, AC, BAB etc), which could be overridden by child characters. Currently if I want to add a new attribute for macro purposes (e.g., add an 'Evil' or 'Undead' flag) I can set a default value at the top level which would propagate down to child characters. A base 'Drow' character could inherit the bases, set 'Evil', 'Chaotic' and 'Elf' flags to 1, and add macros for their special abilities, and I could then create characters for individual Drow types (wizard, fighter, elite fighter etc) without having to manually go through every one by hand whenever I add a new flag or change a macro.
