It would be great if we could orientate the Tabs Vertically, and have the Tabs at the top/bottom/left or right.
It could work similarly to a button bar orientation, and you have an option for which area you want the tabs to be positioned.
A complete Overhaul of Tabs would be appreciated, allowing Tabs to have functionality found within other areas of FileMaker:
TAB Control as a Whole to have an ObjectName, this way we could Get(FrontTabPanel; ObjectName)
Hide/Show Tab Panels by Calculation
Tab Controls to be buttons with Icons, conditional formatting etc.
