Copy and Paste Lists and Tasks
This was a really handy feature in Wunderlist - the ability to copy/paste both lists and tasks...
I had a number of template lists which I could copy if I needed. For instance, a generic list of holiday items to pack which would be copied/pasted each time I went on a new trip.
Thankfully - the excellent integration with Outlook means I can do this at the Outlook end, and it'll be replicated in To-Do! :)
On Web, you can duplicate lists and tasks. On Windows, you can duplicate lists but not tasks.
Basically you can have templates for lists and duplicate them on both Windows and Web.

It would be nice to be able to duplicate a task like Wunderlist could. Very useful to manage projects and work production.
