Design View
When you declare buttons for the control center, you can set their location, height, width, text color, background color, and a hotkey for them.  You can do this from within the PowerHome Explorer, but it's far easier from within the Control Center Design View.  Anytime you declare a button or make a change to a button from the PowerHome Explorer, those changes will not be visible until you close and reopen the Control Center (if windowed.  If the Control Center is set in preferences as a background you must either restart PowerHome or Reinitialize from the file menu).  When you declare buttons in the PowerHome Explorer, they will all default to the same location and same size.  Its difficult to design your Control Center layouts from here, so just let everything go to default.  Once you are done defining buttons, close and reopen the Control Center so that the newly defined buttons will appear.  Next go into Design View by right-clicking on the Control Center whose tab you wish to edit and select Open Design View from the pop-up menu.  You will only get the popup menu if buttons have been defined to appear on the tab.  An empty tab cannot be designed upon.  A new window will open with a copy of the Control Center tab displayed within it.  The Design View window will show you approximate screen resolution bars.  This design view window also has a toolbar associated with it.  There are a number of functions on this toolbar allowing you to design your button layouts graphically.

When working within Design View, you can select a button by clicking upon it.  The button will display as selected by appearing depressed.  Multiple buttons may be selected so that toolbar operations can be performed on all selected buttons.  Some toolbar items are only available when two or more buttons are selected (the size functions) and some toolbar items are only available when three or more buttons are selected (the space functions).  Whenever a toolbar operation is performed, all selected buttons will be deselected.  You can quickly re-select the buttons by pressing the Reselect toolbar item or pressing the F1 key.  When buttons are selected, they can also be manipulated by pressing the arrow keys to nudge all selected buttons in a specific direction.  If you press the Shift key along with an arrow key, you will adjust the size of all selected buttons.  You can also right-click on an area in the Design View and relocate all selected buttons to where you right-clicked.  The buttons will be moved in the same layout that they currently are with the first selected button’s upper left hand corner moving to the spot that was right clicked and all other buttons moving relative to it.

After saving any changes and closing the Design View window, close and reopen the Control Center (or reinitialize if running in background mode) so that the new design changes will be visible.
