The project manager window has been a feature of the Delphi IDEs for years, but only recently (I think it was with Delphi 2005) it has aquired a new feature: You can rename and even move files in it: Just open an existing project of yours (to be safe: Make a copy and open that copy.) and bring up the project manager. It will show you your project and all the files it contains. Now, if you open an explorer window and look into your project's directory you will find, that not only was the .pas file renamed to "MyGreatForm.pas" but also the corresponding .dfm file. That's convenient, isn't it?
