It would help if Gox's new UI didn't suck balls.
Every time I go for a market order, it says I don't have enough funds, when I clearly do. It's so frustrating.
By the time I've refreshed the page, and re-entered the same volume of cash that I put in first time, the market has run off without me (again)
I think it's a vast improvement (although it could have been even better but whateve's) I'm happy that it tells you the fee you will pay.
