I would love to have my buy/sell buttons on the same page as the charts.  Sucks switching back and forth, particularly because the buy/sell interfaces on ALL the exchanges are a joke. It shouldn't be that hard to click your balance, set a price, click "buy/sell all" and have it do the very trivial math that takes your fingers 90 seconds to do.

I have debated creating a GreaseMonkey script to do exactly this that would inject itself directly into your charts page. 1st class support is always better
