I just put up version 2.3 which adds a "Special Powers" tab listing those things your owned advances let you do after the calamity phase, and adds some animated transition effects when you open or close a pop-up to view a single advance' or calamity's details. The visual effects are mostly suppressed if you have set your device to prefer reduced motion.
The Trade card acquisition tab is more detailed, especially concerning the Wonder of the World's power, if you have input your city count.
Coming early next year is another new version that will support game features most of you have never seen. It will also lack a "buy me a coffee" link and that may be a bit of a hint.
