BTC-e support would be the best thing ever. I purchased RTBTC to get familiar with it in anticipation of BTC-e support and really like it!!! One feature that would be nice would be an 'all in' option. You know how on BTC-e if you click on your balance it automatically inputs the total cash/coin amount? That would be nice. Just one small feature. Really great work!
I second the buy/sell all option.
If you click your BTC balance and you have an Order Entry box set to Sell, then that balance will fill in the Amount box.
If you click your fiat balance and have an Order Entry set to Buy then:
- If it's Buy Limit, then it will fill in the Amount field so that you spend all of your fiat at your specified Limit price
- If Buy Market, then the Amount field will be filled in so that you spend your entire fiat balance on coins at the current market price

Is this the functionality you're looking for?
*facepalm* I feel like an idiot now. That is absolutley what I was looking for. Do you expect to add BTC-e and if so, when?
