In the sidebar's drop-down list of Building Types, one is "Manor House/Meeting Hall". These are two distinctly different things that should not share the same sub-category.
I'd like to see the two things split into "Manor House" and "Meeting Hall" under "Type", rather than as one shared selection. This would make pages more accurate rather than implying readers may be able to hold a meeting in someone's house, or trade for a cannister of milk at the local meeting hall.
It makes both options selectable without mixing Manor Houses and Meeting Halls together.
It makes the two types of building separately searchable as well as creating more accurate pages.
To take this one step further, a custom field for users to generate their own "Type". Not sure if this would break the system but just a thought
I could see this posing problems with articles that have already been created with this type...
