Wow such a coincidence! I recently toyed on such a spec for my shell prompt task manager https://github.com/netgusto/tax (I display it in my prompt and my tmux session bar, it's nice to keep current work in focus)

I'm certainly going to look into implementing the spec.

Some questions/suggestions:

    * do you plan support for text unrelated to tasks ?
    * do you plan support for sections / nested sections?
    * idea suggestion: in tax (linked above) we use markdown bold to notify "focused" tasks and sections, ie the one(s) that should be front and center; ex:
        - [ ] **This is a focused task**
