Another day, another merge-request...
Investigating the tasks (x14), it seems mainly to address to-do (x10), with maybe 4 exceptions rather relating to [task-manager] (x30).
Suggestion, as usually: Merge the two, and make one of them a synonym to the other. Re-tag the mentioned 4 exceptions to "task-manager".
As for task-manager (x30) and multitasking (x12) I'm not sure what to recommend. While both are clearly related, they represent different points of view.
