Looks good, left a few suggestions

Just a handful of minor edits. Otherwise, LGTM!

Lots of good updates here! I added a few revision suggestions.

I also suggest cropping the inline icon image saved-query-menu.png to leave just 1 pixel padding on each side, and no border. With all the extra padding, the icon itself ends up looking very small and hard to see.
