We implemented some effects that can be handy when designing a page in our editor. Effects like shadow, text shadow, black & white and blur. These effects can be used by adding them and then configuring them. To do this choose the effect from the selectbox. You will see the effect with icons behind it now. Click on the wrench icon to configure the effect.
If you want to change an element visually on hover you can add a hover effect. These work the same way as the general effects. Add one and configure it. When you hover over the preview square underneath it the effect will be shown on select element.
