Hi guys, I need your help 
I’m creating an app for using on iOS, Android and the Desktop (through the browser).
I would like to have the Tab Controller at the TOP of the screen, not the bottom which is the default.
Because having the Tab Controller at the top of the screen makes more sense when using the Creator app in a desktop browser environment.
Is there a way of hacking Tab Controller to do this?
If this is not possible, alternatively would it be possible to use a Button Bar in a Header bar, to do the same thing as a Tab Controller?
Note: I don’t need to display the page header, as the Tab title is the page header, just like in a desktop apps tab container!
Many thank in advance for your advise,
David
