ToDo list "one task at a time"?

Question

Task Management

Two weeks ago I came across a ToDo sheet stackplanner.com (don't take it as an advertisement). The main idea is that only one task is visible, at the top of the queue. Attention is not blurred and it is easy to focus. But unfortunately the development was stopped (judging by the news) 2 years ago, and there is no hope for the introduction of new features. Meanwhile, I really want to at least put down deadlines and randomly mix tasks.
Actually the question is: are there such services (the main thing is that only the current task is visible)? The platform doesn't matter, whether it's iOS, Android, or just a web application. I would write it myself, but there is no time =(

Answer 1

Here is a source code for Emacs Lisp found on github: ToDoStack .
Not the web, of course, but suddenly it will help.

Answer 2

Similar functionality is available in the MyLifeOrganized program (but this is a program and not an online service). There you can see the entire to-do list, or you can see the so-called “next actions list”, which includes tasks with the highest priority (configurable).
Those. if you have 10 tasks with different priorities, in the list of next actions you will see only a few (one) main ones at the moment. Once completed, the next most important task will be displayed.
