Please note that PhoenixMiner is extensively tested on many mining rigs but there still may be some bugs.
Additionally, we are actively working on bringing many new features in the future releases.
If you encounter any problems or have feature requests, please post them here (in this thread).
We will do our best to answer in timely fashion.
I have a feature request. Can you make it so that mining can be set as enabled or disabled based on the time of day and the day of the week? The reason why this would be useful is certain electrical plans offer reduced rates at offpeak hours in exchange for drastically increased rates at peak hours. Some also exclude certain days of the week, such as weekends and holidays from the peak pricing. This would allow for roughly 80-90% uptime in exchange for 60-70% operating cost.
