New to BGA: iPad problems

[Duckworp]

Hi,
I am new to BGA and play on an iPad. I have two suggestions:
1. It is not possible to chat on an iPad as the keyboard covers the chat area. Can this be easily resolved?
2. Is it possible to add an undo button? I play a lot on yucata where you can reset your turn, but on BGA on an iPad that is not possible.
Thanks
Peter
