In my Fun side of Delphi presentation for the Borland Developers Conference in Nashville I demostrated several ways to customize the Delphi IDE. Two two most useful ones are part of this MyDelphi wizard: you can now have a multi-line component palette, use the palette local menu to change page, resize Delphi's main window, and change the font of the Object Inspector (great for presentations). The multiline status is saved in the registry.
You'll find the complete source code and description in the book Delphi Developer's Handbook.
