Export task list like a template that other users can import
Allow users to export a carefully curated task list that can be used as a template which other Wunderlist users can import as a template to start off with. E.g. Checklist of tasks when moving houses.
It would help with the tediousness of having to manually re-create subtasks, or manually create tasks with subtasks for all scenarios, find them, copy them, put them in the right spot when a simple select from template option would be much quicker and easier.
As long as I can personally import these, and have the option to share publicly or not share publicly, that works for me.
