Tasks is great, except it isn’t possible to get started quickly because there is no way to add a lot of tasks quickly.
I think it would be great if pasting a multi-line text into the task input would create a task for each line. My life would be better 
e.g I have a text list that I want to turn into tasks. Can’t be done as far as I can tell after many hours testing.
I can turn a text list into tasks through Google Tasks, but I can’t move that into Nextcloud tasks (no export, no sync).
csv imports don’t seem to work through thunderbird for tasks. Every other option would require logins or other non-privacy methods.
I am aware that Nested tasks will break when edited in outlook, thunderbird does not support nested tasks either
