Anyone who really wants to adjust their editor toolbars can always install a plugin like TinyMCE Advanced, which lets you reorganize the default toolbars as well as add in extra tools like a table dropdown editor or anchor links or page breaks.

I don't use it terribly often, since I want the sites I manage to have a pretty predictable workflow for training purposes, but when I'm working with someone who has very specific types of content that has been useful.
