With the pager, you can drop tasks from the task manager onto virtual desktops to move the window associated with that task to that virtual desktop.  It would be nice if the same was possible with activites.

Reproducible: Always

Steps to Reproduce:
1. open the activities list
2. drag a task from the task manager to the activities list
3. drop the task on an activity

Actual Results:  
The activity list becomes nearly invisible and dropping on it does nothing

Expected Results:  
Dropping the task on the activity moves it to that activity

There are two other activity widgets, the activity bar and a third-party replacement for the current widget.  Neither of these support this feature, either.
