I use the router config exclusively.

Need a quick way other than visiting the web dashboard and drilling down to find current load of any given server... it's cumbersome to visit the web page, click through the menu, scroll down to country, expand the list, then open browser search to find the server you're looking for.

An API would be awesome. With an API in place, clients could be built for various platforms (windows, mac, ios, browser extension, etc.)

Then when server loads goes nuts I can quickly switch (via my router app) to another server I have already configured.
