With the font toolbar, there's a great deal of control over fonts, but it's made the font gallery negligible.

What I'd like to see is the ability to roll over fonts in the font gallery and have the text change, just like in the toolbar dropdown.

the toolbar dropdown covers the page. So you have to scroll the page over so that the dropdown doesn't cover the text you're trying to change.

The font gallery is already part of the screen and docked off to the right. It would make sense to make use or that space because the font list dropdown and the font gallery list are repeating the same task and therefore one of them is redundant. I'd rather keep both and just fix the gallery, giving users a choice of which one to use.
