I think a working wallet should be the first priority.. I have mined thousands of coins to the android wallet, some show up, some don't... I sent 1000 coins to an exchange 2 weeks ago, and they still have not arrived. Why would I want to mine this coin if I cant spend them.. This should be #1
This seems to be more related to the blockchain not advancing because of a lack of miners than to an actual issue with the wallet ...
