I also have topic-related or project-specific pages where I track their todos. Eventually the current double-page will be full and I also have to migrate there.

I also have topic-related or project-specific pages where I track their todos. Eventually the current double-page will be full and I also have to migrate there. In my daily list I then just have a todo like "do the next thing for project XYZ, see page 42", where page 42 would be the current project XYZ page containing the todo.
