improve visibility settings

Looks like TinyMCE compatibility with some other modules has been a looong standing issue: http://drupal.org/node/72940.

It isn't playing well with http://drupal.org/project/webforms for me, and in the thread trackbacks and other modules are mentioned.

Could the Visibility settings be improved to incorporate some of the things in the thread? Or maybe borrow from FCKEditor where granular control for every input#id is possible?
