Suggestion A levelled turret plot/marker?

[Martin Rudat]

The default game only has a relatively small selection of turrets; it might be nifty to have something that says 'a turret goes here', or 'a powered turret goes here', the idea being that there are a number of mods that add a variety of different turrets, but unless they are added as a dependency to a given city plan, or embedded within a plot, there is no way for those turrets to appear within a city apart from the player building them directly.

The same thing could apply to land mines, and possibly to traps, though I don't think that the different varieties of traps are particularly interchangeable.
