Basic functionality and old boarding passes now lost to the system

The app seems to work ok. But the new version of the app looks a bit different in how it displays info but seems to be equal or lower functionality!? While new App has boarding pass generated and stay within the app it cant be opened with passbook and the app doesnt allow access to old boarding passes I need for expense claims etc.
Its always been a pretty basic app but youd expect it to grow substantially over time.
Would be great to
- be able to select seats within app
- be able to purchase extra luggage
- be able to access frequent flyer profile, history, summary etc
- soviet cut to key parts of Qantas webpage

Hopefully some time and money can be diverted to this at some point please?
Thanks
