I love the monitoring ! I am using MindMiner for quite a while and it's very stable compare to other softs !

Couple of features that may be added on the todolist :
1 - Any version of the monitoring server to be run on a private server ?
2 - Possible to graph couple of stats like the BTC/Day total/per rig or NB worker online
3 - Trigger alerting on Telegram/Mail when losing a Rig or Hash/BTC = 0
4 - Trigger  on Telegram every x to have the stats
5 - Add the power consumption for the calculus of the profitability
6 - Select specific Algo to Benchmark ( instead of disable one by one )
7 - Having a MindMiner Manager to control all miners ( like the proxy )
8 - Integrate HiveOS switching algo

I am willing to pay a couple of bucks on a monthly basis to have these features added.
