Like me, you might have trillions of gadgets on your iGoogle homepage. Though you might already have several tabs sorting gadgets into categories, you might seldom, if not never, visit the secondary tabs because loading a new tab is just too slow and inconvenient. Google engineers came out with a solution to solve this by creating a 'compound gadget' that holds more than one gadget within a gadget separated with tabs.
After adding in this compound unit, you will be able to choose from a list of gadgets that are already in the same tab. But beware, there is one problem (or bug, whatever you call it) with the gadget at the moment, is that once you pick which gadget(s) to include, you will no longer be able to edit the settings of the compound gadget. In other words, you cannot edit the name of the compound gadget, which gadget to included once you have made the initial set up. So be sure to make all necessary customization. By putting gadgets into gadgets, you will find your iGoogle homepage more spacious and allowing you to put more and more (and more) gadgets into your homepage. The compound gadget can be improve to become more user-friendly by allowing users to drag-and-drop gadgets into and out of the compound unit.
|Update: It seems it was my problem only about unable to edit the settings of the compound gadget after initial set up.|
