Maybe this is kind of a strange question, but my client really would like this option.
My client has tens of PDF's and growing with about 4 PDF each year. He wants to offer the option to search in all PDF's from one position. Is that something you can develop within 3D FlipBook?
I do know that there are other plugins that specific offer this functionality, but I first want to check if it is possible within your plugin.And I am not sure if those plugins can search within PDF's that are setup within 3D FlipBook.
