Assigning a subtask to another task or changing it to a normal task

[BestNickName]

In Abeluna, a subtask is created for an existing task. It is not possible to assign the subtask to another task. It would be good if a subtask can be assigned to any other task.
Also, it would be great if there was the ability to make a task a subtask and vice versa.
Nextcloud allows both this via drag and drop.
It would be great if this was also possible in Abeluna.
Thanks in advance!
