Make the Play/Stop button more conspicuous, maybe change its > color(s). Not so hot on this one :-) It breaks the Sugar design guidelines (colour represents user identity). Now I know Walter has quite seriously gone and broken these guidelines with some of his technicolor tool icons in TurtleArt... The shock, the horror... But not sure we should continue that slide in Sugar guideline standards ;-) Pro: Yes, black and white for Stop, and colour for Play is quite visually effective. Con: Once we start to creep into colour tool icons they'll start appearing all over the place and the collaboration colour == identity metaphor will start to break down. The high contrast silhouette of icon shapes is a strong component and differentiator of the Sugar UI design. The current 'Play' and 'Stop' icons are from the standard Sugar artwork set, perhaps we should just improve them. I was never completely keen on both their silhouette shapes being round, or perhaps it would be enough for the fill/stroke to be inverted between stop & play shapes? Eben: maybe there is some design middle ground for having some tool icon colour in the HIG? Perhaps with a strict specification, say like a single colour (different brightness allowed) may be used in addition to white & transparent, but only for toggle or radio buttons to indicate important active vs inactive states? But I'm not convinced. It feels like an erosion of a strong design principle.</blockquote></div> Perhaps, anticipating future collaboration of Physics models, the Play/Stop toggle could bear the color of the invoker. This would provide some additional information on who started or stopped the model. (The toggles are labeled Start/Stop. Play fits the graphic better; Pause--with the player control graphics--may be appropriate and distinguish it from the Activity Stop button label.) --Fred
