Hi Joe,
This is something I have given quite a bit of thought. I think it would be quite useful to allow the SiteAdmin to select whether or not users can choose their favorite editor. Maybe even have an option where the SiteAdmin can select the editors they want to have available to the user. I think this can be a web.config setting as I don't see it posing issues for people with multiple sites. I have quite a few customers who have multiple people editing their sites and usually they all favor a different editor. Myself, I still can't decide which editor I like the most and often times find myself going to source view anyway.
Just my 2¢.
Thanks,
Joe D.
