I think he means tools as buttons that automatically apply the formatting code to the selected text and not the code itself.
I believe him to be quite aware of the formatting code as he used linebreakers in his text, which would already point to him having read the formatting guide.
I actually quite agree to this suggestion, having buttons/tools that help format the text, if and when possible.
I'd also quite like for Hyperlinks to work correctly, be able to add images to the post and maybe even embed videos from portals such as Youtube and Vimeo as added tools.
Maybe even a "spoiler" format tool, making the text hidden unless a "spoiler" button is pressed.
