GuideGuide: Columns, Rows and Midpoints for Photoshop

Cameron McEfee made a neat little plugin called GuideGuide to make setting up a grid system in your comps easy:

After many hours spent meticulously nudging nav elements and building grids for layout in web comps, I began to wonder why Photoshop didn’t have a grid tool like InDesign. At a certain point I decided to stop thinking about it and just build a tool to do it for me.

GuideGuide lets you find midpoints, make margins and create rows and columns in a snap in Photoshop CS4 and CS5. Get version 1.0 and see how to install it here.
