Hello people, >I'm always amazed how educated guesses like the above can be >made without seeing a single line of Logic code. A little birdy told me so. Apparently, the user interface connects the user to the internal data models & functionality. Tweety says that design can be examined simply by operating the software. >"Emagic R&D staff have poor design skills since otherwise features >as easy as multi-level undo & redo would long have been >implemented". Ooohh, that's not a very nice thing for you to say about Emagic. We were saying, tweet, tweet, that transition to an OO design is neccessary to implement such features. And that they'd be relatively easy once that transition was made. Any supposition about poor design skills is purely yours. Cheers, Thomas
