Always show rich text editor when available?

This is mostly a question, and possibly a feature request depending on the answer.

Instead of having a button to turn the rich text editor on & off, why not just always show the rich text editor when a channel supports it?

We've had some confusion among our agents who didn't realize why the options weren't showing up and didn't realize they had to click the button to enable the rich text editor.

Are there some cases where rich text is supported but the rich text editor needs to be disabled? i.e. when you can't just "not use the rich text editor buttons"?
