Do you want a different Dock for every day of the week? Do you get bored with the same Dock but don't want to mess around changing it? Or do you simply want to bring more order to your Dock?
If so, iDock could be your answer. iDock allows you to have as many docks as you want opening up a whole new world of organisational possibilities. For example, you could use iDock to sort your applications, stacks, downloads and more according to what you're working on or what you need.
iDock works via a simple switcher mechanism. Simply open iDock and click on either the "Change Dock" button or the "Go To Dock" button. If you choose "Change Dock" you can use the arrows to scroll through them. If you chose Go To Dock, type in the number of the dock that you want to go to and click Go To Dock. Dock changes take no more than a few seconds but you might find that sometimes your dock disappears. If this is the case, then you need only click "Help, My Dock's Gone!" and it will reappear.
iDock is a useful tool for anyone that needs more organization in their Dock although the likelihood of anyone needing more than 2 docks is questionable.
