Over the edit box, there is a "Syntax highlighting" button (its icon is a marker angled at 45 degrees and it is to the left of "> Advanced > Special characters > Help > Cite"). It is a very helpful feature that is not on by default.
Consider: The
Hahn-Banach theorem article has a lot of info about linear extensions of linear functionals that does not fit well in that article. Maybe move that into an new article called "Linear extensions" that could more generally also have info about linear extensions of linear operators? Or maybe "Linear and sublinear extensions" to include info about extending seminorms and sublinear functionals (also in that article)?
