Previews some new UX features in the upcoming 2.23 release. (41m), Sept 25rd, 2014.

Out of the box Open Atrium is shipped with default branding;

1. The logo next to the main menu
2. a Powered by Open Atrium image in the footer
3. An image (2 images actually) at the login screen.
4. A default home page

Of course, it's also easy to override all of this in your site-specific theme, so if you create a subtheme of oa_radix you can add/remove whatever you want.

Open Atrium is shipped with Open Atrium Radix, a sub-theme of the Radix theme for Panopoly. Check the project page of Radix for further background information on this Bootstrap based theme.
