One nice feature to have would be a longer history when looking at the minute tab. Values could be buffered in the page, so I could see the minute values for more than the last 90 seconds or so. No need to buffer in the Flukso, I don't think. If I navigate away from the minute tab, the values can be thrown away so, when I come back, I have to wait for the history to build up again in real time. But it would be cool for experimenting with various devices to see how much difference it makes to "turn off this or turn off that."
