It took me a while to see the white on light grey label saying Anonymous.
Also, for new users it may not be obvious that that's where you need to press to log in and they might just wander away before finding it.
Suggestions:
- obviously fix the label colour to follow the theme
- allow the account list to open inline in the settings window if it is short.
- open it automatically, exposing the "Add Account" button, when it is empty.
- make the account button in the bottom right corner go to an account select-or-create screen when you are not logged in.
