Hi michelem,
switching to CGminer or BFGminer instead of the CPUminer would turn Minera into "just another Raspery PI solution". I tried a lot of images based on several versions of these miners, not finding a better working setup. For me CPUminer has some nice features:

• autotuning for the Minis - haven't tried it my blades so far
• beside the switching issue it's way more stable than any of the other miners I've tested
• in combination with your ui and your monitoring option it's "just working"
• most important: it's clean and light - not overloading the PI like some other solutions

From my point of view it would make sense to fix the CPUminer and improve the ui step by step - just my opinion.

Looking for some unique features for the next releases:

• common dashboard for multiple Minera instances with control and not only status
• extending the summary for pool hashrate and last share information to show min/max/avg
• adding something to switch pools on profit
• ...

bye
