During your lessons, you'll notice a 'Lesson Materials' section on the left-hand side of the interface.
When hovering over the material thumbnail in the library, a preview pop-up window will appear, allowing you to remind yourself of the material's content before placing it on the board.
By clicking on the material with the left mouse button, it will be placed on your whiteboard and immediately visible to your students.
If any changes are made to the material during a lesson, these changes won’t be saved permanently. The version of the material stored in this lesson will remain as it was before the lesson began.
You also have the option to rollback all the changes made during the lesson, restoring material to its original state. You can do this by clicking a "Restore" button on the whiteboard toolbar.
