datasette-apps 0.2a0

This article announces the release of datasette-apps 0.2a0, a tool that allows apps to live inside Datasette. The update introduces two new features: app_debug(), which lets the Datasette Agent open an app invisibly in a sandboxed iframe and run JavaScript tests to verify functionality and measure element dimensions, and app_list(), which lists apps the user can edit for agent access. These enhancements improve agent-driven app development and testing workflows.
