Used several exchanges and didn't see this or close function even once... So... Probably there is none
that sucks - how are you supposed to do comparisons to make decisions.
My preference is to mine coins in the tank and sit on them - then sell once they go up.
seems like everyone rushes to the coins that are selling high, but by the mine you mine anything worth while they've dropped again.
Yep it sucks indeed. Maybe someone should "borrow" this idea from Yahoo. Mtgox comeback easy?
well - if 'hackers' could penetrate the system there - LOL....
they should have taken the software while they were at it
I'm also surprised no one has came out with this in the fashion that you'd see on google finance where you just fill-in "add a symbol" and get a nice overlay.
What i've done in the past, and this is a pain in the ass, is use a window transparency program to put a semi-transparent window over another, keep in mind the scales all need to be the same (i.e. the charts need to have same price min and max)
Actual Transparent window works good and is fairly simple:

http://btccharts.com/ will let you load different charts side by side and if you turn on the universal cursor (something like that) it will tell you the price and % diff of where you mouseover for each exchange.
Still would be nice to have a simple chart with multiple exchanges overlayed
