Hello. I am glad to announce Presenty - new user interface framework for Pharo (with MIT license). I publish my current version on http://www.squeaksource.com/Presenty.htmland write first articles about Presenty on blog http://smalltalk-presenty.blogspot.com There are some problems with current implementation. But step-by-step I fix it and improved it. And I have many ideas about Presenty future. Main goal of Presenty is platform independent programming of user interface: Pharo can run your application on any OS. Presenty can present your application on any OS. With Presenty you can easilly write UI applications which can be configured for all "user" platforms: mobile phones, tablets, desktop computers and others. Presenty is based on Morphic and I think morphic can simulate every platform appearance and behavior. And I think simulation is easest then supporting native backends. I have two commercial applications for my company which based on Presenty. So it is really usable although many common UI stuff absent and some bugs exist. One is touch screen oriented application (for basic computer, not mobile device) and second is basic desktop application (driven by mouse and keyboard). It is different applications for different kind of users but its use same components of tasks and domain objects. So when we implement new logic of user interraction it appears on both applications but user takes it with different look and feel. There is problem with speed of presenty application. For my case cog performance solve it. So I don't worry about it. But problem relates to #veryDeepCopy method of morphs. It is very very slow. This method is used for view creation from prototype morph object. I have fix with special methods for copy prototype morph. But I don't use it yet. Now I prepare presentation for ESUG. So I can take into account of all your comments and questions. Best regards, Denis
