BTW do not spent lot of time on Enyo. In fact Enyo is not at all a pre-requisite. At end we could hope to be JavaScript framework agnostic. If you follow threads in this mailing list, you could have enough lucky like me to learn a new JavaScript framework each day :-) So yes, being JavaScript framework agnostic is interesting.<o:p></o:p></span></p><p class=MsoNormal><span lang=EN-US style='font-size:11.0pt;font-family:"Calibri","sans-serif";color:#1F497D;mso-fareast-language:EN-US'>The issue about “console” is that the “console-message” is standardly use to get output from the “console.log()” JavaScript function. So, it’s not at all dedicated to communication between JavaScript and the embedding WebView. The hack that I’ve used it that if the console message is prefixed by “enyo://” it’s processed by the framework like a message to Sugar, else the framework just pass the message. You could see this in the “Log” activity when you run Grid paint activity. So the idea of improvement is to find a less hacky way to interface Sugar and JavaScript. It’s one of objective of the IRC meeting.<o:p></o:p></span></p><p class=MsoNormal><span lang=EN-US style='font-size:11.0pt;font-family:"Calibri","sans-serif";color:#1F497D;mso-fareast-language:EN-US'><o:p> </o:p></span></p><p class=MsoNormal><span lang=EN-US style='font-size:11.0pt;font-family:"Calibri","sans-serif";color:#1F497D;mso-fareast-language:EN-US'>About UI, yes the main part of the work is to do CSS files to reproduce the Sugar UI.
