To upgrade from an older version of Dockyard, hold command and drag the old icon out of the menu bar. Then simply double-click Dockyard.menu, log out, and log back in. It's that easy!
Dockyard is a very handy program that lets you switch your Dock into different configurations at will. However, you need to install a program that allows third-party menu extras, such as Unsanity's Menu Extra Enabler. Once you have installed a program like this, simply double-click on Dockyard.menu to have its icon appear in the right-hand side of the menu bar.
If you have not used Dockyard before, you will start with a single dock named "Default," which contains the current contents of your Dock. To add another dock, choose the Create New Dock… option from the Dockyard menu. Choose the name of your dock and the items in it, then press OK. Now you should have two seperate dock configurations! To switch between them, either choose the corresponding menu item from the main menu, or the "Change to dock name" option on a submenu.
Rearranging docks in the menu is also easy. Simply choose the Reorder Docks… command and drag your docks into a new order. Deleting docks is just as easy: choose the Delete Docks… command and choose which dock to delete. And renaming works exactly the same way, except you enter a new name as well.
A useful feature of Dockyard is the ability to open a dock's submenu and open an item—without even switching to that dock! Just be warned that the submenu for the current Dock will not update until you change to a new dock. But that's OK, because you can just use the real Dock to open these items.
The Dockyard menu extra is fully compatible with Dockyard Manager and the Dockyard widget as of version 1.6. This means that any changes made in any of the three programs will be reflected in each of the others.
Finally, the newest feature of Dockyard is designed for Mac OS X Tiger: the ability to switch Dashboards as well as docks. This feature is disabled by default (in order not to surprise anyone coming from Panther), but can be enabled from the About Dockyard… command. There is also a black-and-white icon that can be turned on or off from here, designed to match the other menu extras in your menu bar.
You can uninstall Dockyard by holding command and dragging the Dockyard icon out of the menu bar, then releasing the mouse. You are then free to throw away Dockyard.menu (if you get an error message, try logging out and logging back in before emptying the trash).
If you see another file in this folder with a name like "Dockyard.1.menu" or "Dockyard 2.menu", just ignore or delete it. This file shows up when you do not use Mac OS X's default zip archive handler and has Dockyard's file icon inside. It is not necessary to run Dockyard, and can be deleted without harm.
Dockyard will run on Mac OS X 10.3 or later, but Dashboard switching will automatically be disabled on pre-Tiger systems (for obvious reasons).
In Mac OS X Tiger, the Dashboard is run from the Dock. This means that switching docks will also cause the Dashboard to restart, regardless of whether or not you have Dashboard switching turned on. This is normal and unavoidable.
