This mod adds the Chunk Activator block, which keeps the chunk it's placed in loaded. There are no GUIs, no fancy range selectors, no player login tracking -- no frills. Just a simple, single chunk loader. If you want to load a bunch of chunks, just place a bunch of them. Since it simply wraps the vanilla /forceload command, ops can find which chunks are loaded with /forceload query.
Yes, I implemented this in the laziest way possible.
and my code is garbage but it works
