Minimize When a tool is minimized, the title shown in the toolbar is visible as a button. To restore a tool to its full size, double-click on the minimized button. The delete option will completely remove the tool from the room. Once it is deleted it cannot be restored. Properties You can change the title in the toolbar to something more descriptive and you can change who can access and change your tool.
Authority is based on group membership.
Groups are assigned the authority to change a tool. The current state of a tool may be saved at any time. Each time you save a state, you are saving a version of the tool complete with its contents at the time of saving. To retrieve a version, use the Versions option. You can then select the version you would like to restore.
