Progress bars

You can now add a progress bar to flash messages. The progress bar has a transition-duration CSS style property set to its element, with the duration being the flash message's timeout value. Essentially this will animate the progress bar smoothly until the timeout elapses.

To use:

Ember.get(this, 'flashes').success('Great success', { showProgress: true });
