From feedback from Any To Do customers, we realised that emailing a full list was not a function that was used very often. In order to keep Gneo as streamlined as possible we have therefore removed some functions which were in Any To Do. If this is a requested feature we will look to include this in a future release.
You can however email individual tasks by going to the 'Show Details' card view from either the List or Forecast view, by swiping from right to left, and then clicking on the 'Share' button. From here you can email individual tasks.
