This may be asking a lot, but it would also be nice if you could reference a 2d symbol for the profile on a path object(extrude along a path).
This would allow me to just switch out the 2d symbol's profile when a client would like to change the design of the crown or baseboard, for example, to a different shape, rather than having to edit each path object to trade out the profiles manually. This is a very common work flow issue that I on run into...
