SmartSVN simplifies the handling of 'Tags' and 'Branches'. Both 'Tags' and 'Branches' are no native SVN concepts, but can easily be handled by the help of copy commands (Advanced Copies). SmartSVN provides special commands for this task, which are based upon the copy commands. All of theses commands require to have your repository layout properly configured in the Project|Settings (Repository Layout). The commands are available from the Tag/Branch menu.
