Yeah, all coins in one request that would be great. As of now I have to request one coin at a time with custom hashrate and this hits "429 Too many requests" error sometimes. What's the server policy btw?

Also, is it possible to include the default calculator's hashrate into each coin's JSON? This way we could download the whole bunch in one setting and recalculate custom hashrates locally by simple multiplier. This could alleviate server stress as well.
