In FastReport 2018.4 a very interesting feature appeared - duplication and removal of the report pages in preview mode. Let us be clear. We are talking about the pages of already built report. That is, you can select a specific report page and clone it as many times as you want, or delete the selected page. In this case, there will be no effect on the template itself. Even if you have only one page. To get everything back to its original state - simply build the report again.
