Hello Chris Thierry,
Currently we don't have special navigation control, but our Toolbar having Hyperlink buttons and a Frame is great option.
About the disappearing of the TileView, can you give us more details? Or if you have project that demonstrates the issue, you can send us and we will check if everything is ok.
