I did mention that, but it's a connected workspace so each of these apps can talk to each other. Think like notion's "/link to database" function. Basically, none of these apps are designed to be standalone SaaS products, but instead they can exist in a workspace together.
Apps can subscribe to updates from other apps so a photos app could aggregate media from across the workspace, and also platform-wide actions like a custom right click menu that pipes into specific app functionalities.
