This is the first release of CMF Portal Layout.

From the description:

"CMF Portal Layout is kind of like CMF Porlets. The idea is that you can define a portal layout by defining rows and columns and filling these up with "Layout items" (like portlets).

Layout can be applied to folderish content, and defines the layout for the folder and subfolders. Layout on a folder can be overwritten and changed depending on permissions, on a subfolder.

At top level, manager can "lock" certain rows or columns, or selected layout items in rows and columns. Manager also defines a "Main slot", where content is presented. Rows and colums definitions are then used to generate the ZPT templates for the site.

User can change the layout of their memberfolder, by adding rows and columns to their main slot, and add or remove layout items to the existing layout, if the inherited layout items aren't locked."
