implement click polylins callback and drag create gantt task

[jhwqthjy]

Are there plans to implement these two features:

1. Click callback events for task connection SVG polylines, providing information about which two tasks are connected by the clicked line.
2. The ability to create new gantt tasks by dragging in the zoom area on rows where start and end times have not been configured.

Hello,

Thank you for suggestions. Both features look reasonable, we will add them to the tracker system and consider their implementation in future releases.
