As well as application icons, Android allows users to add widgets to their launcher screens.
K-9 has a small number of built-in widgets to show information in the launcher.
K-9 Accounts Widget
The accounts widget allows you to have an icon that links directly to an inbox - either a single inbox, all messages or the unified inbox.
The icon for this is the K-9 mascot, the same as the application icon.
K-9 Unread Email Widget
The unread email widget is connected to the unread messages for a single inbox, all messages or unified inbox.
The icon for this is an envelope.
