What it is: Technically, this isn’t a widget, but a handy shortcut that’ll give you driving directions home with just one tap. From the menu where you usually add a widget, tap “add shortcut,” then choose “Directions and Navigation” (or “App Actions,” then “Directions and Navigation” on Motorola phones), and enter your address.
Why it’s a good widget: You can do this trick for any address, but home is probably where you’ll want to go the most. With this button you won’t have to type in your address over and over.
