Do you want to create scenes and design levels faster?
ShiftMove is an free editor plugin that adds extra-functionality for cloning objects on the scene view (like in Autodesk 3ds Max). Now you can hold shift, move object and create any number of clones. Objects will be placed at specified distance.

Just take a look at video, ShiftMove in action!

You can download it for free from Unity AssetStore.
