So the header nav parts are great. Perfect addition for FMGo. However I did notice something weird in FMP when using header parts. One user needed to access on a small screen laptop (Mac Air 11") and sized the window to 75% to fit everything on screen. Problem is the header nav does not resize and any controls that are placed near the right side disappear off screen. I guess there cannot really be one layout for all devices. I understand why this is happening. I just do not understand why there cannot be some sort of anchoring that will allow objects in the nav parts to float left when the window is resized.
Any known way to work around this issue beside having double layouts?
