• yarn start [iwa] as a root command with iwa being optional and allowing for a selection of which iwa you want to start
• yarn build [iwa] is already in but having an iwa parameter would be useful.

@Shard yarn start without an IWA does not seem useful? If you don't supply an iwa what does this do, start all of them? If we did that they would be on different ports which means you can't share localstorage and authentication status etc so this would seem to be of limited use.

yarn build [iwa] already exists just through a more wordy yarn build --scope entry-iwa as it is a lerna command and --scope always works.

The idea would be to use yargs or something very simple to give you a selection of which iwa to start/ and yea when it comes to this it's another case where it could be done now with yarn workspace entry-iwa start but i wanted to jot down some ideas Ive had to make the root yarn commands simple and straight forward.
