Ask HN: To-do list that lets you put a lot of detail in each task

I know that these days there are more to-do lists than Chinese people. I was looking for one that will satisfy my needs, and after about a dozen that didn't I decided to ask here.

I'm looking for a to-do list that lets you put a lot of detail in each task. Most to-do lists only let you put one line in the task, while I want to write pages of text about each task. I want to keep track of my progress in each task. It's more for mini-projects than for tasks. I will have a lot to write about each project. I'm not even sure if what I'm looking for will be called a to-do list or something else.

Does anyone have a recommendation?
