Moving an Analog To-Do System Into a Plain Text File
Recently, I've tried moving my analog to-do list methodology into a giant txt file. Each new day is added at the bottom of the list.
- > New Task
/ > Task carried over from the previous Day
X > Completed Task
? > Outstanding Question
! > Priority Item
In practice, it looks something like this.

I was inspired by this thread on Hacker News.

Other than the ability to search my notes someone had the suggestion of using colons as tags. :feature-a, :feature-b. I might switch that to hashtags, but it would create a mess if I ever switched to markdown.
