Tim,

Creating the next phase of GUI design is a laudable goal, but for now, I have to be able to speak my current and near-future users' language. I am game to discuss anything more that you want to consider, but a viable cross-platform solution to meeting current users' needs is anything but premature.

Todd,

I had forgotten about the costumes - now I really want no part of Tweak

Costumes are in my opinion one of the more useful parts of the tweak design. You an change the look by changing the costume. Now tweak events... that's a different story. Nice idea but living with them in practice has been a real pain. Debugging when there are dozens of processes running, each handling an event related script has not been pleasant. I'm sure there must be a solution but we (as in 'the Sophie team' have not found it.

Perhaps we can offer a choice between Morphic and "The Welch Thing" on a per-use basis.

That would be 'the Welsh thing', if you don't mind, (http:// www.etymonline.com/index.php?search=welch&searchmode=none) or 'Ariethfa Ffenestri' or just ffenestri. Remember that ffenestri is *only* a system for creating and manipulating host windows and allowing us to draw upon them. Someone needs to implement whatever higher level code is need to make meaningful use of the window. Morphic, Tweak, even MVC could all do so. My preference would be to see something based on Cairo(http://cairographics.org/) since that offers quite good quality, reasonably portable, vector based drawing and fonts and image composition.

I really think that the conversations about use of MVP, MVC, whatever a re very premature. Right now I'd urge people to be thinking about what a UI should be able to do and not worry about just how to do it yet. What sort of interactions are needed? What widgets will support them? What sort of UI creation tool (s) would be nice? What sort of presentation devices should be supported - big screen, little screens, colour only or monochrome as well, touchscreeens, projected giant displays, web browsers via Web2.0-whatever ?

Take the time to really work out something sensible. Document what is worked out. Work through scenarios of use and programming of the design.
