I’m surprised you disable the google drive feature. We’re not that worried about local files leaking even if the laptop is stolen, given apple’s hardware encryption.
On the other hand, the workflow of “manually download file, modify file in app, manually upload file” is clumsy and error prone, often leaving files stranded on the laptop.
On the gripping hand, google drive (as it is called again) seems to crash every few days so perhaps your restriction isn’t much of a limitation :-(
