Thank you for your post.
With a FileMaker Pro 12 file being accessed by FileMaker Go 12, the Web viewer displays on my iPad, iPhone, and iPod touch. Can you provide more information about the contents of the Web Viewer? That is, what site is being accessed? Is the information static or read from a field?
The Toolbar can be removed by tapping the gear/wheel icon in the upper right corner and setting "Show Toolbar" to the OFF position.
The Header and Footer will scroll if you are in Form View. However, in List View or Table View, the Header remains.
I recommend you enter your product suggestions into our Feature Requests web form at:
These entries populate a database file that is hosted by Development and Product Management, where they are then discussed and considered for future releases. Although I could paste your suggestions into the web form, there are a couple of questions asked that only you can answer.
