Hi RacerX,
sorry I didn't mean to put down or offense anyone, I was just trying to explain what my goals where. I guess it's better to say what you want to do rather than what you don't want to

I truly apologize if I hurt someone.
I don't know Stone Studio so I can't comment on it. But did I miss something about Imaginator? I tried it quickly and it really seemed to be just like CoreImage Fun House. I mean it's already a lot of work if it started from scratch. The comments on versiontracker really seemed enthusiastic about it, that's why I tried it. But since I am always concerned about drawing, either pixel-based or with 'artistic' tools à la Painter, I didn't find it very useful for my personal needs. That's why I said "seems useless to ME". I am sure there are lots of uses for it if you know how and when to use it.
In the version of Imaginator I downloaded some time ago, the only paint tool I saw was one that drew simple lines but it was very slow on my poor 12" iBook. Maybe it's quite different on an accelerated machine. It just appeared to me that I could hardly use it for creating artwork. It looks good for effects, but then again FunHouse does pretty much the same. Again, I didn't test it very thoroughly those are just the impressions I had when I quickly tested the app.
BTW when I said my app was going to be able to create "website design" I just referred to the dimensions of graphics. It won't be an app for very big images, at least not soon, since this would require advance memory management (like photoshop does with blocks). But designing websites or anything else requires being able to paint with various tools, masks, layer masks and such things. Probably the only function directly related to web design I may add in some later version would be the ability to save slices (like ImageReady/PhotoShop does) as an HTML table (because that's all I did use myself in such software).
Now about my personal background, I have never been an Apple developer. But I have never really been a Windows developer either

Before OSX I spent some time on Linux but really got fed up.
I have programmed mostly in java and php. Recently I have been into java mobile applications (
http://mobile.link-u.com/). About BeOS as you might have found: I was quite a fan of it. I actually bought the operating system when R3 appeared on intel (in 1999?). And I even wrote a very very buggy painting app for it a long time ago while learning C. It was called Natural Paint, then Photon (when I abandonned it and release the source code). Finally it was renamed to BePhotoMagic by the people who finally realized the source-code was too buggy to be usable as a basis for a good program... But my skills have improved since then, well, I hope so!
As for my personal experience, I had worked on macs earlier but I bought my first mac ever in december 2004, so ChocoFlop is actually my first ever mac program and my first ever objective-c program, so I am not a specialist nor do I have close relations with Apple as your friend seems to have but I really enjoy developing with Cocoa and OpenGL. ChocoFlop is a good occasion for me to learn about these technologies but I also plan to make it a consumer-oriented app.
Finally, about the full screen mode I just happen to like working on a empty uncluttered canvas and I always liked that feature in older apps like Deluxe Paint, a long long time ago.
