Unfortunately I know almost nothing about vscode extension underlying technology and my question was more meant to be a super careful feature request .
I have observed that some Julia beginners with low CS background (but strong scientific skills) tend to put off engaging in effective project-based development. They can waste a lot of time missing the benefits of Julia projects (Revise.jl, dependency management, environment compilation, IDE support, git tools…).
I think that this feature could help Julia adoption smoothing the Julia’s learning curve.
Of course, such a feature would also help general user like me (already convinced by the project development necessity), to start new project faster. In particular for super small projects were you experiment a little with some packages.
