I've used various todo list systems & software, and I hate them all. 

Here's roughly what I want. I'll try to remember to update as I think of things.

## Projects

So I can

* make plans
* group actions together
* see progress
* limit work-in-progress

## Contexts

So I can see only the things that it's possible for me to do right now.

Really, this is flagged for dependencies.

## Technology

* Android support
* OS X support
* _Encrypted_ cloud-based storage
* Offline usage
* Flawless synchronization
* Pluggable storage backend so I can comply with security policies of various employers
* Import and export
* Open format

## Philosophy

* Easy capture of random ideas and things that come up
* Minimize sense of obligation for following up on random ideas
* Limit work-in-progress
* Remind you of _why_ a thing is important
* Because I'm a human, that's often _who it's for_ – a face
* Encourage me to say 'no' to things
* Work on *one thing* at a time
* Emphasise and reward things done, encourage the transformation of done tasks into meaningful achievements
