On April 24th, we'll be rolling out a few more improvements including some optimizations to Webmail that will improve scrolling speed and responsiveness for users.
New WYSIWYG Toolbar and Brandable Login Page
One of the more visually evident updates will be found in the WYSIWYG editor toolbar. We're making some changes to the toolbar to make it easier to use, and those changes will have the added benefit of providing improved performance.
A before and after of the WYSIWYG toolbar is attached to this post. You'll note some minor changes in icons and alterations in how the toolbar is laid out.
We're also adding a new brandable element for those who are using the custom branding features of Webmail. Later this month, you'll be able to set a background color for the webmail login page.
The new toolbar and brandable element can be seen in the Production Test Environment now. We'll roll out the changes to all customers on Clusters A and B on April 24, 2013.
