Official management panel
I created http://proxy.xmrig.info/ management panel for xmrig-proxy.
Key difference from other panels, you can manage multiple proxies and group it as you need.

Panel is web based, single page js application, server used only for serve static files, all data stored in your browser and all communication happen from your browser.

* This is first technical preview version, not all features implemented.
* Because of a [bug](https://github.com/xmrig/xmrig-proxy/issues/245) better if you update proxy to v2.6.5, but it not strictly required.
