This feature came out a few years ago but I still use this almost every day. The ability to copy a row from one page to another is quite an achievement which other page builders have yet to master so well. This was introduced in OptimizePress Version 2.1.8 (which was released early 2014).
Copying and Pasting rows is a great feature that will let you copy a row to other pages for pages built using the Page Builder/Live Editor (on the same site). Check out the video below to see this AWESOME new feature in action (Note that this video was created some time ago – apologies for any novice mistakes lol)!
One final thought about this is if you copy a row that has a lot of custom CSS then you will also need to go into the settings for the page and copy that code over to your new page as well.
