I like the "new" Review and Update Typedef feature.
What I don't like is handling the CASE structures I have connected to enums when the enums update. The constants for the enums update fine, but the selectors for the CASE structure are not included in this operation. I really wish these could be handled as pseudo-constants for enums, allowing re-assignment of cases with a preview of old and new values. I've started adding an enum constant to each case just to serve as a reminder which case it's actually supposed to be. And that feels kludgy.
Currently, case structures auto-adapt to enum indices. I'd like that to no longer be the case.
