A resourceful Flash developer, Jakub Kozniewski, created a Flash application, CS User Interface Builder 1.0, to help build interfaces for scripts. Apparently, he is working on a 2.0 version.
It's great to see the Photoshop Scripting eco-system starting to grow. I'm fascinated by Photoshop Scripting the same way I was by web development back when I was in college in the 90's. From the first table I built to the first roll-over I created using JavaScript, each step was exciting, even if things like these are considered mundane by today's standards.
I know I felt that same excitement from my first "Hello, World!" Photoshop Script. It can only get more exciting...
Well Jacob´s website isn´t available at the moment, but I know of his works and this one is an awesome, too. I am proud poland can offer that such a great developer.
