Developed a granular planning view for the glpi-project/glpi repository, enabling users to filter planning items by their completion status and improving dashboard clarity. The work involved implementing a new filter to include or exclude done events, refactoring the event display option from display_done_events to state_done for better maintainability, and ensuring consistent filter application across all planning dashboards. Leveraging JavaScript, PHP, and UI/UX principles, the developer focused on feature-driven development and code clarity. This update reduced manual filtering, enhanced planning accuracy, and provided users with more control over task visibility, contributing to a cleaner and more maintainable codebase.
