BlockSoft has introduced software designed to customise the Dock within Mac OS X 10.5 'Leopard'.
Docker 1.2 (donationware) allows Leopard users to switch between 2D or 3D dock, or customize the Dock by individually changing the colour of and style of Dock elements.
The software also lets users introduce their own images to replace icons in the Dock. It also lets users of Mac OS X 10.2 to 10.5 access normally hidden settings, including controls for dock size, additional animation options, and more.
Newly-introduced elements in the software include a new user interface, the option to only display open applications in the Dock and various tweaks.
Previous experience using software that tweaks the operating system shows that it's wise to disable such software before applying Apple system updates.
