Currently, the Hint message UI consists of two sections, where each section only gets a small amount of screen real-estate due to competition with the other sections. It might be better to embed a tab-folder in place of those two sections where the source is one tab and the preview is the other. I dislike only being able to see one at a time, but for the sake of screen space, it might be the best option unless we decide to move it "back" to how we originally had it (as it's own UI section apart from the Hint UI).
