Konstantina Zerva developed a drag-and-drop image upload feature for the maths/moodle-qtype_stack repository, enhancing the STACK editor to allow direct image insertion for content creators. She implemented this workflow improvement using JavaScript and PHP, focusing on front end development to streamline media embedding within STACK questions. The new functionality reduces the time required for content authoring and increases reliability by simplifying the process of adding images. Throughout the month, Konstantina aligned her work with the project roadmap, validated integration with the existing editor, and prepared the feature for deployment, demonstrating a focused approach to targeted feature delivery without addressing bug fixes.
