This looks awesome! Thank you a lot!
It is very helpful.

And since you are onto it I must add another thing that is somewhat related.
Let's say the 1hour graph. The whole graph is 1hour "wide".
If you have just started the miner/client it is not.
It is much shorter instead and only shows couple of minutes.
And another one, which I will try to describe by memory, since I don't have it
"in front" of me right now:

1. It is 10:00 now.
2. My miner froze at 9:20.
3. I rebooted at 9:40
4. The graph shows as straight line between 9:20 and 9:40 instead of not being there at all.

Maybe after you declare the miner as dead and email alert also zero the graph?

I am sorry if my reports are annoying you, but I think you should know about them.

So I don't know if you have a feature request list but here is one:
"Group miners for remote control."
It means - switch all my 7950s to a X11 pool, and 280x to a X15 pool...
So define groups (farms) and switch them in bulk.

Keep the good work!
Thank you again for your great piece of software!
