The message list widget, when running on Android 3.0 and higher, supports:
- Scrolling
- Checking mail
- Clicking on individual messages to open them
I could make message items clickable on Android 2.*, but concerned about the amount of system resources that would use. Android 3.0 has special functions that help reduce system memory usage in this case, Android 2.* does not (I'm talking about a PendingIntent object for each message item).
