During November 2024, Vaani enhanced the Mail Spam Filter interface in the sg-au/sg-main repository, focusing on streamlining user interaction and improving efficiency. She implemented UI/UX improvements using JavaScript, CSS, and HTML, introducing a more descriptive user guide and refining input styling with a grey background for clarity. Vaani enabled Enter-key submissions for email and label fields, accelerating data entry, and added dynamic enable/disable logic for Save and Download actions to reduce user errors. The work addressed a single feature with no bug fixes, reflecting a focused, incremental approach to front-end development and user experience optimization within the project.
