I like it as it behaves the same as the old QB 4.5 programs (copy text etc.). Besides that, you can make nice utilities that run in CMD prompt.
I've already been able to swat some persistent bugs, that were slowing my code down a lot, by _ECHOing variables inside of certain iterations to the console. Then I could say, "Hey program, why are you doing THAT calculation when it's not necessary". I sometimes talk to my programs... ;)
It's incredibly helpful to be able to watch were things are going behind the scenes. Until Fellippe did this video I was just shooting in the dark trying to figure out what was eating up processing resources.
