Great work on those new tables, that's a huge improvement IMO. It might be nice to default sort by most recently updated, and to make the tables collapsible, but that's relatively minor.
Regarding classifying pages as short or detailed, we could use page data size. You can see the size of a page by looking at edit history. It seems the smallest detailed page is Overgrown PD at ~7kb, and the second smallest is Remake PD at ~9.5k. The largest small page is Deistic at ~11kb. Perhaps we could say that a page is detailed once it reaches (or is just short of) ~10kb? That would mean moving Overgrown to short and Deistic to detailed but otherwise everything already fits.
