For discussion in sprint meeting...
If there are multiple WikiProjects on the item, then that section kind of takes over the grid. (I know the example screenshot is from a partially-broken WIP -- just using it here to show the size of the WikiProjects section.)
One thing that we can do is to filter out WikiProject sub-pages -- just show Military history, and don't show the "Military history/United States military history task force". Eranbot's page filters those out.
We could also consider showing WikiProjects horizontally, as seen below. That could free up some more room, which we could use for longer page titles.
