Gav: I've used this for prototyping couple of things. It's not superexpensive and it does a good job of sketching the ideas you have in your head? Ye, for sure. And the extra thing that i really want to talk about is lay out. So if you're going to put ike two buttons next to each other, then you just want him to take up 80 % of the space combine and have a little bit of mar or something. You know, you could use absolute positioning. Even if people don't have the book, they cand pr go dig it up. Same for all my stuff. Wo alexander says, interesting.
