Extremely annoying that when doing 'load snapshot', you cant tell what the actual full list of pip packages + custom nodes are without exporting the json file

This goes for snapshots in general. We should have a way to view the full current status of a snapshot from within the app without needing to export.

In the case of Load Snapshot, we cant even see what is the thing being applied without this.

Start by tracing the snapshot viewing and Load Snapshot flows in the desktop app. Define a way to inspect the complete snapshot status, including pip packages and custom nodes, without exporting JSON; done means the full information is visible in-app before applying a snapshot.
