Get ToolsDaemon! thats ToolsDaemon NOT ToolsManager.
it basically gives you a Start Menu on the top instead of the bottom or more precisely, just adds all you applications the top menu you already have. Its faster than anything of its kind on the Amiga because it doesnt add graphics which weigh down the OS. Get it with Magic Menu, it makes ToolsDaemon look better.
If you want to waste ChipRam (Aka gfx memory) with some sort of nice dock....you can cheat by simply redisgning your icons to look good if you dragged then close to each other, and once you do that, simply use the "Leave Out" command on the menu to leave your favotire apps on the Workbench screen, and it will look like a Dock but run as smooth as all you other icons.
