SHORT ANSWER: 5
Check out our video tutorials, I drone on a bit, but I do go into a great bit of detail on how you can add and remove menu buttons.
We have updated our tutorials, to include a video on how you can add up to 7 horizontal menu buttons.
First, download this file, extract and save to the ‘flash’ folder of your web.
This will over write the ‘horizontalmenu.xml’ file, so first back the orginal file UP!
