Hey BitcoinWisdom, it's me, your loyal supporter and fan

Any chance you could maybe increase history size of charts? What I mean is: if I set the chart to, say, 15 min, I can "drag" it back a few days, then the history of that time interval is over.
Practically this means, I cannot go back to, say April 10 in the 1 hour chart.
I know, there are other sites that can do this (btccharts, for example), but I really like your interface and all, so I'd prefer to do it on btcwisdom.
In another reply you already said you don't want to increase the "max zoom out", because then candles would get to thin, but let's say you leave the zoom out untouched, but allow us to drag back further into the past... would that be possible without too much work?
