Hi, I was thinking that new users can get much help from did you know tips. But I don't like regular tips, which are shown in a modal window that just bothers the user. This are shown at the top of the window and should rotate automatically after some time. I developed the code in squeak4 because I had an image already open, and now when I open it in pharo I see that I have SystemWindowButton class missing. What steps should I follow to port that from Squeak? You can see a screenshot below, and are invited to write more tips, like keyboard shortcuts and anything you think is useful. By the way it is in http://www.squeaksource.com/PharoTips and you open it doing PharoTipsMorph show. Hope someone likes it, Javier. -- Javier Pimás Ciudad de Buenos Aires
