In the Passage guide, I noticed that mousing over a commentary's title gives the "title page" of the resource rather than a preview of the hyperlinked article. By contrast, I discovered today that mousing over the same commentary in the Explorer window gives exactly what i would expect, a preview of the first couple of paragraphs of the article. This mousover preview is wonderfully useful, but as the explorer window is not yet rearrangable, i'd like to see the Passage/Exegetical guide fixed.
I debated whether this was a bug or a suggestion...but for the life of me, i can't imagine why someone would want to read the title page of a favorite resource more than once. The important thing here is the linked article. In addition, the little star icon refers to the article rather than the book, so the mouseover could serve as a nice reminder of the article's content.
