For assistance in creative mode building, a creative mode terraforming item can help in big projects. These would be similar to the building items (maybe a different texture). These can automatically change by biome, if that is possible to code.

Ideas:

Hill: Similar to a barrow,  this has stone two or three blocks down.

Peak: Taller form of hill with more exposed stone, useful when making tall hils or small mountains,

Blouder: Is already a feature in the mod, made spawnable, would have a different stone depending on biome.

Trees: Larger trees can have building items, including but not limited to: Mirkwood trees, large shire trees, fangorn trees.

Cavern: A large halfcircle which can be used to make dwarven or goblin settlements without the messy bombs.
