Superb, well-focused extension Rated 5 out of 5 stars
I wanted a vertical toolbar, I got a vertical toolbar. What a concept! You get what you want! And only what you want.
I love having the additional buttons. They are compatible with my Aeon themes, so the themes will have support for some of the built-in buttons, like print preview. I note that I will have to figure out how to make vertical separators show up on the vertical toolbars - that's the only bit this extension lacks. Some of us like to split our buttons to make them easier to see.
Speaking of easier to see: with the changes to another extension, the extra buttons it supplies are hard to make out against the gray background of the default theme. The optional button borders this theme supplies are exactly what we need.
