From what I can see on the screenshots, the receiving page shows an address that starts with 1 which means there is no SegWit support? I suggest you work on that one. Another feature that I would like to see in a wallet would be the ability to connect to my own node instead of relying on your servers.
We support SegWit adresses (both: bc1*** and 3***). You can't generate such an address on purpose inside the app, but still can send/receive assets to/from those addresses.
Concerning node connection unfortunately, we are not supporting that feature. As I know, overwhelming majority of our competitors don't support it neither.
