Pages in Dalo do not have any functional meaning. They are there simply as a navigational aid or like they would be in a real-life notebook.
In long-list family of methods (AutoFocus, FVP...) all tasks belong to one long list. The same is true here.
The pages are there simply to make it easier to parse tasks, a handful of tasks from one page is easier to parse than 100s in the whole list.
