This will allow you to do multiple things, such as:
- transforming multiple entities at once
- cloning whole groups of entities
It will also make larger setups much easier to work with.

I'm also working on a bigger feature based on this. You'll be able to select a large area, have the plugin automatically create entity groups, and then generate new blocks from those groups that can directly replace the original setup, all with full undo/redo support.

I've been pretty quiet over the last month because real life got in the way a bit (I moved apartments and did some other things), but I'm now fully back, so updates should happen much more regularly again.

I'm planning to release the next update right when Update 5 drops.
