You could already add custom icons to the home screen, but with this update you are now able to upload custom icons to your navigation tab bar at the bottom of the app.
With this update we've added a couple options to the custom list:Images and thumbnails.
Images will cover the entire width of the app and do not show any text, while thumbnails will replace the icons.
To set this up, edit your list item and select from the dropdown either thumbnail or image.
Separate Online Giving Screen
You will now find a "Online Giving" item in the configuration menu that lets you configure a distinct Online Giving screen that is separate from the other screens in your app.
