Manually set someting as 'DONE' or 'TODO'
Right now, if you want to complete a Todo you have to do some action OR you need to click
Done in the Todos view.
That is not a nice workflow if you're coming from email, deep in a thread.
I propose we add a button / link somewhere to mark something either as
Todo. Not sure where / what would be easiest without overloading the UI.
@skyruler you have any ideas about the flow and placement of such a button?
