+The TaskList component has been deeply refactored with a modular design, improving code maintainability: + +**Refactoring Results:** +- Main component reduced from 686 lines to 361 lines (-47%) +- Logic separated into 5 specialized composables by responsibility +- Each module has a single responsibility, easy to test and maintain + +**Composables Responsibility Division:** +- `useTaskListLayout` - Virtual scrolling and layout calculation +- `useTaskListColumns` - Column configuration management and style calculation +- `useTaskListResize` - Container size monitoring and ResizeObserver management +- `useTaskListEventHandlers` - Global event handling and scroll synchronization +- `useTaskParentCalculation` - Parent task data calculation and task tree traversal + --- ##
