Worked on the JabRef/jabref repository to enhance the OpenOffice and LibreOffice style selection dialog, focusing on UI reliability and user experience. Addressed a bug where the delete button for internal CSL styles was invisible, which previously led to user confusion and hindered style management. The solution involved refining JavaFX UI components, removing dead zones in the delete column, and improving tooltip handling for better guidance. Incorporated the ValueTableCellFactory to streamline cell behavior and updated import orders for maintainability. All changes were implemented in Java, with a clear changelog entry documenting the fix, resulting in a more intuitive and maintainable interface.
