I want to implement Autofocus system in org-mode using agenda views. Autofocus is a time-management system, where you write tasks in a lined notebook with 25-35 lines on a page and you don't start working on the next page until you processed the current page.
By default agenda collects all todos and throws them in a buffer altogether. I want to break these todos by blocks of 20 tasks, for example, so i can process one batch of 20 tasks, then another batch, and so on.
How can i do it? Any solution from using org-mode built-in trick to some emacs lisp snippet is appreciated.
