it was possibly mentioned before, but altcoins bidwals somewhat counter-intuitive. I.e. price is in bticoins, but volume is in basic units. It's quite hard to udnerstand deepness of orderbook with that picture. Like is that 20000 altcoins good enough wall to protect this level?
Can you add to wish list the ability to "reverse" orderbook for counter currency?

To be said, BTC will fit more

I know it's all numbers in the head and just need to get used too, but we human used to "base values" currently there is 2 base values at your site: BTC and USD Well litecoin for the some extent (being used to that) but I guess you udnerstood the point.

I also udnerstand that it's will be very unstable orderbook, cause it have to be recalculated with each tick, but that could be possibly avoided if change recalc interval like 5 seconds or soemthing
