Oh jeez, it's coming back to me now. Yikes, what a terrible use of classnames. I'm sure they thought they had a good reason for it, but to me it's kind of a failure of a feature implementation if most of your userbase ends up not just ignoring it but outright deleting it because it's useless to them and just creates clutter.

Dreamweaver did have one saving grace. It had this code editor cleanup mode that removed empty and redundant tags, and at one point they added a neat option to remove Word document tags! From what I remember, it was pretty accurate and helped clean up a lot of shit. Unfortunately, it was unable to clean up code that it created itself.
