This is a cool project - however Mac and Windows only...most likely because they are creating the toolchain for this.
I would pay money to get something like this inside vscode - which is an ecosystem that works great on all platforms and provides the hooks to build something like this.
On that note, I think microsoft is making a mistake by not creating an app store of sorts for vscode. VsCode is as good a desktop developer marketplace as the play store is for mobile apps.
I wish that plotly had built this inside jupyter (where their Dash product competes against Streamlit) or vscode. Building a desktop installer toolchain from scratch, does not make sense.
