// IMPORTANT: If you want to change the default value of "LevelEditor_Layout_v1.1" or "UnrealEd_Layout_v1.4" (even if you only change their version numbers), these are the steps to follow:
// 1. Check out Engine\Config\Layouts\DefaultLayout.ini in Perforce.
// 2. Change the code below as you wish and compile the code.
// 3. (Optional:) Save your current layout so you can load it later.
// 4. Close the editor.
// 5. Manually remove Engine\Saved\Config\Windows\EditorLayout.ini
// 6. Open the Editor, which will auto-regenerate a default EditorLayout.ini that uses your new code below.
// 7. "Window" --> "Save Layout" --> "Save Layout As..."
// - Name: Default Editor Layout
// - Description: Default layout that the Unreal Editor automatically generates
// 8. Either click on the toast generated by Unreal that would open the saving path or manually open Engine\Saved\Config\Layouts\ in your explorer
// 9. Move and rename the new file (Engine\Saved\Config\Layouts\Default_Editor_Layout.ini) into Engine\Config\Layouts\DefaultLayout.ini. You might also have to modify:
// 9.1. QAGame/Config/DefaultEditorLayout.ini
// 9.2. Engine/Config/BaseEditorLayout.ini
// 9.3. Etc
// 10. Push the new "DefaultLayout.ini" together with your new code.
// 11. Also update these instructions if you change the version number (e.g., from "UnrealEd_Layout_v1.6" to "UnrealEd_Layout_v1.7").
