This is something that would be nice to have.

I think this falls within the scope of hematite_server.

Sorry to pull up this dead thread

The client still needs to be able to edit rendered chunk, without having to reload the entire thing. Basic testing functionality could be added to be able to remove a block by clicking, and a block by right clicking (just using whatever is clicked to choose the block i.e. right click on wood, new wood is placed next to it)
