When I add a package in the repl I can see it in Jupyter and my editor, but not in Pluto. I hate to dupe packages and waste limited disk space. Is there any way to make Pluto coordinate?

you’re not duplicating packages because there’s only one source code depository, what is maintained independently is `Manifest.toml` which only records the environment.

Thanks. But why won’t Pluto recognize what I load in the REPL?

because each pluto notebook now records its own environment

To add to jling’s answer. You can activate an enviroment manually, e.g.  
`import Pkg; Pkg.activate()`. (Of course, this has disadvantages as well.)  
See: [Package-management advanced-set-up-an-environment-with-pkgactivate](https://github.com/fonsp/Pluto.jl/wiki/%F0%9F%8E%81-Package-management#advanced-set-up-an-environment-with-pkgactivate)

The recommend way to use Pluto is not manually adding any package at all. Just type `using MyPkg` or `import MyPkg` and Pluto automatically takes care of installing packages and pinning versions for reproducibility.  
You only need to manually add packages if they are not in a Registry (General or custom registry).
