Thanks for the response, but I was asking about Bluebeam Revu.
find the highlight tool and add it to the toolbar
you can customise/remove all the toolbars
in full screen you can also add the highlight tool
you can add "my tools" where you can put all your tools
you must read the instructions of bluebeam revu
i have bought it 6 months ago and still learning
ocr feature is also very important however is available only on the extreme version
