Worked on the home-assistant/frontend repository, focusing on enhancing the Tile Card Editor by implementing a configurable hold action feature. This addition allowed users to define specific actions triggered when holding down a tile card, with the default set to 'none' to prevent accidental activations and improve overall safety. The feature was integrated directly into the visual configuration editor, making action mapping accessible as a primary setting for both users and automation workflows. The work involved frontend and UI development using TypeScript, with attention to configuration management to ensure reliability and user control. No bug fixes were recorded during this period.
