I noticed another glitch in the software when I was saving an unpublished post. When you press Save and Continue Editing the editor switches from Visual to Code and back to Visual. So while saving you are temporarily faced with the code while you are actually working in the Visual mode. I think this is another example that demonstrates that the visual editor is an added option (see my previous post: WordPress problems: Visual editor gone (fixed), or: A glitch in the software)
What is even more interesting is that I recently discovered that the visual editor offers even more options than it actually displays. This extra toolbar is not activated by default nor is there a button to activate it. The extra formatting options were hidden from the general user until someone noticed it and posted it to a WordPress forum. Activating the extra options is done by pressing Alt-V in Internet Explorer or Alt-Shift-V in Firefox.
The standard visual editor toolbar
The advanced visual editor toolbar
But everytime you press Save and Continue Editing the extra toolbar disappear again (not with automatic saving) so you have to press Alt-(Shift)-V again and again until you have finished your post. To solve this issue a Visualize Advanced Features plugin has been released that adds a button to your standard visual editor toolbar that enables you to toggle the advanced options on or off (and leaves the options on or off.)
