User blog comment:Random-storykeeper/Wikia HUDs: Header and galleries/@comment-4628859-20141110191638

If the header is the blue and light blue box at the top that has a drop down list, I'd say I prefer the old style as it didn't have a gap in the drop down list and it looked slightly better (though the last bit is just my preference).

As for the galleries: I don't really like the huge amount of empty space it leaves around images and the captioning is strange looking. However, I think what the gallery does to pictures would actually work better for thumbnails as often for thumbnails the size of the image limits how long the captions will be before they stack (but then the galleries aren't for thumbnails).
