How can I show hidden cells in `Pluto.jl`?  
Specifically, if you open [this](https://github.com/JuliaAcademy/Decision-Making-Under-Uncertainty/blob/master/notebooks/1-MDPs.jl) notebook in `Pluto`, you will not see all the other `using` statements after

```julia
using Plots; default(fontfamily="Computer Modern", framestyle=:box) # LaTex-style

```

but they are present in the plain `.jl` file, and are executed when `Pluto` opens it. Is it possible to see that within `Pluto`?

There is a little eye-symbol next to each Pluto cell on the left side. When you click it, the source code of the cell is shown/hidden.

It was not that. I think it was that the cells are present, but they are not evaluated in the order the show up in the notebook.

The evaluation order of Pluto cells is determined automatically by their dependencies. It is in general independent of the cell ordering shown in the notebook.  
The cell order in the notebook.jl file corresponds to the evaluation order (not the one shown in the notebook) so that the .jl file is executable stand-alone (without Pluto).

I see. But if you execute that jl file in Julia, not Pluto, you will get an error, because at the time the struct `GridWorldParameters` is defined, the struct `State` is not defined, no?
