Tasks in multiple lists
I would love to have tasks in multiple lists so that I can share specific items from a private list with coworkers, or collaborative lists. That way I can still overview the complete todo-list, without having to split lists. On the other hand colleagues and friends can work on my shared tasks without seeing my private tasks.
My thought about this idea is more along the lines of shopping. I like to have lists for specific stores, but sometimes items I have on my list could be from any store. It would be great to be able to have the same item/task in multiple lists and if it is checked or removed from on list it will be the same in all lists it is a part of.
This is a feature that I have wanted since I first started using wunderlist. I removed my vote here though because I found the same request with more votes here:
We need to consolidate our votes onto one request if we want Wunderlist to notice the request :)
