Charts... I want all of them, and I want them configurable.

Take a look at the logarithm charts of price over difficulty and difficulty over price specifically.

Also, please incorporate a live ticker that users aren't forced to refresh the page hundreds of times a day.

Leverage.

i want one-click exchange between Bitcoin and any currency on earth - in both directions.

i want to be able to exchange BTC for any currency, and have that currency deposited into any bank - no matter what the status of that account might be to the regulators in my country (the US).  i don't mind using tor, or a VPN.

i want no records kept after transactions are successfully completed, to the satisfaction of both parties.  so it would need to be established in a place where that is possible.

i don't care about short-selling, long-buying, credit default fanciness, or anything other than a pure exchange.

but YMMV.

"buy it now" or "sell it now" as opposed to some type of order matching - like when ebay produced the 'buy it now' feature. So a list that people can view and respond to.

Some people just want to buy or sell a bundle of bitcoins, not have to place orders.

Trading from wallet directly to bank account. I send my coins to the buyers wallet he sends cash to my checking/savings account.

 No intermediary means no central account to ban. I don't know if this is possible but that's what I would like to see. It increases liquidity and protects bitcoin.

If you think that is worth anything

What many people are describing is a feature list for the front-end to the exchange, more like what a brokerage would provide.

I would love to see exchange server software that exposes an API only. The server would provide live data over Secure WebSockets with a nice fall back (AJAX, JSONP). Any exchange operation could be performed over the API - Buy, Sell, Short, Cover, account, order book, trades. You could require users to authenticate over OAuth or something like it so that API calls can be traced to an account.

Be sure to publish thorough API Documentation - as in this: http://dev.twitter.com/doc

That way, whoever is implementing the exchange has the core software written for them, and they simply create the interface software on the front end. They could limit the interface with the server API to a web-based front end or expose it to the public for app creation, etc.

Thank you all so far. Very insightful.

Let me state that payments will be sent out at an exchange rate of $30/BTC. This will happen within the day.

I'm a portfolio manager for an investment fund, so I'm very familiar with the requests mentioned. But let me warn you: a casino-type atmosphere (and that's what it is) of get-rich-quick "market makers" that add pseudo-liquidity as I'm seeing here is borne of nothing but greed. And it doesn't last.

You want bitcoin to thrive and be decentralized? Assume the average bitcoin user is of below-average intelligent. Make it easy for the masses. Forget the geek speak. Forget the pipe dreams of some wanna-be forex speculators that have little real world experience.

Think of a bitcoin exchange in terms of the people you see at the grocery stores, the bank, the gas station, anywhere really. People that know NOTHING about finance or technology. Could your mother or grandmother use any bitcoin exchange?

Many people are just now hearing of bitcoin, yet when they go to investigate it, all they see is confusing, unwieldy gibberish.

A lot of you guys have dollar signs in your eyes, but you overestimate your own knowledge. You'll actually get richer in the long run if bitcoin offers sustainable and easy exchanges for the masses, not just a means of speculation. You want brokerage services? Fine, but the only reason brokerage services work for other currencies is because those other currencies have far greater liquidity and velocity than bitcoin. Don't get ahead of yourselves. One thing at a time.
