Yes, a description would be very nice. For some, if not most buildings the effect building/removing them has on the resources is indicated by arrows to the right of the icons, but e.g. for lumber mill and chop block there is no such indication. (Maybe a bug?) And of course if a building enables new features, this can be found out by accident only - if you have the bonfire surrounded by buildings, you may never become aware that special buildings can be built around the outpost.
So, originally I based the idea around the accidental discoveries (e.g. you can build specific buildings only if you have a specific tile next to it), but as you pointed out, it can lock out players out to discover more of the game.
PS: Lfzinho, you get more wood when chopping down the trees if you have a chopping block :)
