Users should be given a high level overview of functionality they can trigger when activating the LaunchIntent for the first time (currently they only get this information in the reprompt).

App icon is washed out when using dark mode and app not in focus (also on Mojave)

Currently, the user needs to log in separately from the flow of dragging a widget to their homescreen. It's possible to add a widget without being logged in, which isn't very useful.

If the user installs the app, then goes straight to add the widget the log in flow should first be presented

Various URLs in the readme still refer to getmondo.co.uk and need to be changed to monzo.com or they won't work.

You should be able to see subcommand help message without passing in the access token:

$ monz balance --help
Error: To authenticate and use Monzo public API you need to pass (or set as environment variables) either the access token or all of client ID, client secret and authentication code. For more info see https://github.com/pawelad/pymonzo#authentication

There is a fair amount of code that is not documented inside the readme, go through and add it in.
