Settings stored in localStorage are not utilized

[burtonr]

The "darkMode" and "groupMode" values are stored in localStorage so that the settings are reused when the app reloads.

However, these settings are not respected when loading the app. Adding console.log statements in the places where these settings are read, the log shows the default store value, then shows the updated state. The second log shows the proper setting, but the app is not re-rendered to use those settings.
