Rollback and reset feature
The Rollback function is symbolized by a little clock icon and can be found on the upper right corner of the editor, to the right of Preview and Publish. This functions allows you to visualize the last 30 changes done on your website, chronologically ordered from the newest to oldest, and restore any of these versions.
When styling an element you will see the Reset icon on the left side of an option. This function allows you to reset a specific element to its original design, (the design that comes when the module is created in the first instance).
To use the reset function - Under the styling tab of an element, if you hover the cursor on top of any option, the Reset icon shows up on the left. Click on it if you wish to revert the styling of that element and don't forget to click on Save to apply the changes or cancel if you no longer wish to modify the element. Bear in mind, this will remove any styling you may have applied here.
