Twitterrific retweeting and quoting help please

Hi,

I've recently installed twitterrific and am unsure about a couple of things. If I do "retweet" on something, will that retweet straight away or will it allow me to edit it? Also, I was hoping to quote from someone's tweet. But when I chose "quote" an edit box comes up with the tweet on the screen - but the tweet isn't in the edit box. So does that mean it will add whatever I put into the edit box before appending the quoted tweet? I was hoping to be able to select the text of the original tweet.
