I love this app, but sharing specific project with my co-workers is a must if I'm going to invest in it.
although such feature is not available in Todoist right now, you're welcome to try out our other service - Wedoist http://wedoist.com designed for team-oriented project management.
is it feature will be available in todois?
I like more Todoist design and tasks structure.
It will be good if my wife can fill my shopping list from home while I at office.
we will integrate Todoist's features into Wedoist and vice versa in future development. Feel free to vote for this request in our Votebox:
For now, as a workaround, you could buy a Premium Membership (just $14 a year for a limited time only!) and you would be able to add tasks via email (the mail's subject would be the task name and its body - the task note). Each project would have a specific address and you could add your wife's email address to your "Shopping" project and she would be able to add tasks by sending mails to the unique project's address.
