Planned features and known issues #

Extend the Tab API to better control its navigation stack. Most things the built-in Navigator class has, and a few more.
Integrate the Router class or write a custom implementation, for how to specify pages to be pushed.
More customization options for panels and the tab bar and ability to set different themes for panels.
Cupertino and Material versions.
Adding an option to limit the level of nesting. Currently is unlimited.
Clone tab
Adding a new tabs does not scroll the tab bar to bring it into view. To be fixed soon.
