Hi.  I'm the original author of Miner Control.  I stopped supporting the app several years ago and recommended anyone still using it switch to Nicehash Miner.  Their interface is much better than what Miner Control can offer and there aren't really any competing pools left out there.  Back when I first wrote Miner Control, there were several multi-pools out there so the app served a good function.  The market has changed since then.
