I noticed in a week-old post about Visual Studio 2005 enhancements that one thing being looked at is “rich formatting.” Now, that doesn't really say much, but I'd like to see a customizable code formatter built into the IDE. Personally, I don't like what VS does to my code by default - it's not bad, but I prefer a few minor changes. I'd also like to force things in certain places to keep them logically grouped together.
I know that some of this can be handled by FxCop, but as far as I know, FxCop doesn't reformat the code, it just identifies inconsistencies.
The biggest place where I get annoyed is HTML reformatting. I abso-friggin-lutely hate VS's HTML formatting. If advancements could be made to the code formatter that would make it flexible enough to specify templates for all languages, I would be quite a happy camper. I guess we'll see.
