Yes this is a Lightroom Blog, but when something interesting happens with the ‘daddy’, Photoshop, it will be worth a mention.
Adobe Configurator will be out soon on Adobe Labs and it is a really interesting customization utility for Photoshop CS4. It allows you to create your own custom panels for CS4, which can contain the most frequently used tools, scripts, actions etc. It uses the Adobe AIR platform and John Nack has a blog post about it, with links to videos and screenshots.
When you get CS4, if you do, then run and fetch Configurator, it will really open your eyes!!
