6 major cons:
1. No options like -r and -R (similar to ccminer), can't loop for failover, etc
2. No API.
3. After startup I see per-card hashrate... but some time after it not displaying anymore
4. Sometimes it just hangs after swith to dev fee mining.
5. If program terminated, windows appear, with suggestion to End Task... not good for looping.
6. Build f....g linux version!

Please add API support as soon as possible.
Also, it would be great if the API behaves in the same way as the one in CCMiner. That way we can just replace CCMiner with your program.
