Bowing to your demand,
Now I feel like a jerk...
we bid farewell to rounding. The only requirement now is 0.1 btc minimum to buy or sell!
That's good news - it brings you more into line with the other BTC exchanges, though I realize your goal was to be more like a professional currency exchange. My only concern with that goal was that if Bitcoin appreciates the way everyone hopes it will, then the 0.05 thing is simply a high barrier to entry.
Have you given any thought about implementing an unbacked transaction queue like what MtGox has? I didn't really understand it at first, but it's actually a rather convenient feature. I can initiate a deposit, and then if the price is right when the funds hit, a queued-up order goes through and I don't have to keep checking on it.
Please don't consider that a "demand" though.
