The Corona Power Tools, introduced in Corona 11, offer a set of different instruments to simplify the manipulation of objects, which in previous versions had to be done manually or with the help of third-party plugins.
Those tools are:

Object Replacer – Swaps out currently selected objects in the viewport with objects added to the "Replacing Objects" list.
Pivot Placer – Simplifies object pivot placement by aligning it to the object bounding box or a specific point.
Transform Randomizer – Randomizes transformations of selected objects by adjusting their translation, scale, and rotation along the specified axes within the defined variation ranges.
Scene Cleaner – Allows to quickly clean-up a scene.
Selection Randomizer – Allows to pick an exact number of items from the selection, based on the selection count or a designated percentage value.
