Summary: I like to set up window layout defaults for all of my projects. This can be done with "Make Layout Default" in Xcode. However, the layout default doesn't remember which columns I have displayed and not displayed in either the Groups & Files section or the main file list section in the project window. Steps to Reproduce: 1. Clean install Xcode 3.1.1 2. Open an Xcode project. 3. Select the header in the Groups & Files list, and change which columns are displayed. 4. Select the header in the main file list, and change which columns are displayed. 5. Under the Window menu in the menu bar, select "Defaults...", and press the "Make Layout Default" button. 6. Create a new project. Expected Results: The new project has the same columns displayed as the previous project. Actual Results: The new project has the Xcode default columns, not the columns displayed by the previous project. Regression: This has been an issue in previous version of Xcode too.
