Batch Ops™2 was the first ops tool. Before even Hard Ops. Now that this tool has made it over to 2.8 there have been many enhancements and improvements for the next generation of Blender.
The team behind this has been instrumental to both Hard Ops and Boxcutter and this tool is another part of the puzzle for providing an effective and unified workflow now encompassing selection and application on a global scale.
This tool starts off simple but the heavier your scene gets, the harder this tool works for you! It’s like having the Infinity Gauntlet for scene data. *snap*
