Creating, Editing, and Testing Scripts (The ExtendScript Toolkit)
When I first started writing scripts for Photoshop, I used a plain old text editor. It worked fine, but it was a somewhat laborious task to write the scripts and then switch over to Photoshop to test them. Plus, troubleshooting the scripts was a difficult process, as well. Then I discovered the ExtendScript Toolkit in Photoshop CS2. Thankfully, it's a script editor that was created specifically for editing scripts in Photoshop and it really helps speed things up.
