I have a file called TODO.diff, which leverages my editor's syntax highlighting.

An example would be:

  ! A header (PURPLE)
  *** Important *** (SOLID BLUE BACKGROUND)
  Text (WHITE)
  + A finished task (GREEN)
  - An unfinished task (RED)
  --- (HORIZONTAL RULER)

As someone who's gone from to-do list tool to todo list tool, I have now settled on paper and pencil. I have a little notebook I carry around with me. Every evening I jot down my "shippables" for the next day into a new page. I have a separate page for long term goals like "get a gardener over" that I review constantly. And that just works really. Kind of gtd and part of another method I can't recall :D

I asked a question relating to tools for a number of things, including to-do lists earlier this week, and a lot of people gave some very very useful answers:

Myself: Currently any.do and/or a notebook, but looking to move to a wiki, or org-mode.

I have never found a better to do list app than http://dynalist.io

Before that I used Workflowy for ~4 years. Dynalist improves on Workflowy in virtually every way, and its creators listen to their userbase closely.[1]

Things.app (macOS / iOS)

The word "simple" gets thrown around a lot in software marketing and GitHub readmes. That said, having used Things extensively, it truly strikes me as having the perfect balance of simplicity vs features for a todo/GTD system.

For personal to-do lists, I use http://www.toodledo.com/ which is great for having many options (occur every month, every 2 weeks, last Wednesday of the month, etc.), and syncs between mobile and web.

For work, I basically use pen and paper or slack reminders or self chat.

Surprisingly, no one here seems to be using white board and marker or just sticky note on desk.

While I do use todo.txt or Task (CLI) but I also rely on sticky notes or whiteboard for keeping my Todo list always in front of me.

I've settled on Todoist. It's not awesome but does the job especially for recurring tasks. But more and more for work I've found myself using a little notebook or a small stack of index cards.

I also use this. I mostly like how you can set up "projects" and invite people to the list. So I have work projects but also things like "Shopping list" which I share with my partner and we both use the phone app.

I made tasklater.com to keep long-term tasks off my day-to-day list.

And I made tuduli.com to manage day-to-day todos, since I was emailing myself todos anyway. So this keeps them all in one email.
