We haven't tested the drag and drop of GanttTasks with the standard WPF Drag & Drop mechanism - note that this will require a lot of custom code and at the moment we haven't the resources to implement such an example.
The most priority tasks that we have for the Q3 release are:
- Resource view - grouping tasks by resources.
- Serialization of tasks, resources and relations.
I am afraid that we cannot tell at the moment which of these will be included in the release. We will be able to provide more information soon.
We are sorry for any inconvenience caused.
