Only reason it didn't get noticed sooner was because only the categories were missing. Had it been on one of the earlier galleries and not the last one, I'm sure we'd all have been wondering why Drive's gallery wasn't showing up. Instead, we thought it was a bug related to categories. Ah well. No need to delete that page after all. But it does need improvement.
