[Feature Request] Add possibility to move top level task list into another task list

[janvlug]

I would like to be able to drag a top level task list (as shown at the left of the tasks web page) into another top level task list, so that it will appear there as a sub task.

My use case: In this way I could clean up the amount of top level task lists.

Do I understand you correctly, that you want to move all tasks of one list into another list?

@raimund-schluessler: Yes you understand me correctly. And the moved tasks should be in the other list under a top level task with the same name as the task list that is being moved.

Maybe it is a bit more clear if I explain it by using screenshots and URL's:
Imagine that there are to task list:

• https://example.com/index.php/apps/tasks/calendars/tasklistA (referred to as tasklistA)
• https://example.com/index.php/apps/tasks/calendars/tasklistB (referred to as tasklistB)

Now, I would like to be able to move tasklistB under tasklistA. The URL for tasklistB as mentioned above would disappear, and tasklistB would appear under tasklistA as this:

The URL's woud be something like this:

• https://example.com/index.php/apps/tasks/calendars/tasklistA
• https://example.com/index.php/apps/tasks/calendars/tasklistA/tasks/<uuid of new task representing tasklistB>.ics
