Project "todos" are called *issues*.  They can be inspected and
modified using the `issue` subcommand.

Let's say the new car you are designing with your peers has a problem with its flux capacitor.

```
$ rad issue open --title "flux capacitor underpowered" --description "Flux capacitor power requirements exceed current supply" --no-announce

The issue is now listed under our project.

```
$ rad issue list

Great! Now we've documented the issue for ourselves and others. But wait, we've
found an important detail about the car's power requirements. It will help
whoever works on a fix.
