It would be nice to easily be able to move questlines (e.g. by clicking on an arrow like in Better Questing). With moving questlines I mean e.g. switching out questline 1 with questline 3 in the image below.

Related to this issue is #489, which targets the same problem, but has a different suggested solution.

Even tho this issue is different to #489 I'll close it because it is a duplicate
