I work with code which references functions defined in a package developed side-by-side
with the current environment/file. The implementation of the function `view_modes` is
reported as not found, however. This function is defined in `BioImageVib`, which as
the status show is `dev`ed.
I wonder if anyone else is seeing this?
On Windows 10, with Julia 1.7.2, the newest VS Code (1.64.2). Julia extension 1.5.11.

Check the “Julia env” status bar item and set it to your active environment, if it’s not already,

It is correctly set to my current environment (`BoneShaker`). This environment uses `BioImageVib`
as a package.

`BoneShaker` in fact has no source of its own beyond `export`s of functions defined elsewhere.
```julia
module BoneShaker
__precompile__ (true)
using BioImageVib: simulation_name, update_simulation, load_simulation, find_or_compute_mesh
export simulation_name, update_simulation, load_simulation, find_or_compute_mesh
using BioImageVib: extract_frf, plot_frf, clear_terminal
export extract_frf, plot_frf, clear_terminal
using BioImageVib: view_mesh, view_image, view_modes, view_shape, view_points, image_to_mesh
export view_mesh, view_image, view_modes, view_shape, view_points, image_to_mesh
end # module
```

Sebastian: would you _expect_ this to work?

Might be a variation of [LanguageServer does not index active project/package (julia-vscode/LanguageServer.jl#988)](https://github.com/julia-vscode/LanguageServer.jl/issues/988) ?

Looks like it might be: when I `add` the package instead of `dev`ing it, I get the symbol look up to work.
