Test Queries
This is to give you a feel for how the game actually spawns scenery in. The game will always use a primary tag (floor, lamp, etc..) and then generally one or more specifiers, like an Environment tag, or a Monster tag, or a Station tag. You can see what scenery pieces can be spawned, for some common queries.
Tag Report
This is good for seeing if there are any problem with the data, this allows you to quickly see what scenery is assigned to what tags, and if there are extra, floating tags that maybe have been incorrectly entered.
