In rippletrade.com/#/send I've tried to send full balance of my CNY.RippleCN to another account and it was not as easy as I'd hope. The problem is that the balance had over 10 decimal digits and I couldn't simply say "send all". And I didn't want to end up with balance like 0.0000XYZ. I finally placed the caret in "Recipient will receive" and then left the cursor over balance to see the full amount in tool-tip. And retyped the full value. But this is far from ideal UX.
Am I missing something or is this missing feature? I'm using Chrome.
