As you can see I have named various groups like Navi , Apps , Dev , Desktop and so on so how did I do it ??
Step 1: click windows key to bring up the app screen
Step 2: press ctrl and mouse wheel down or ctrl + shift + – key on key board .
This is actually called semantic zoom where you can see a complete view of what you have .now rght click to bring up a bar from the bottom click on name group to name the group .
Not its simple as that and done .
Hope you enjoyed reading.
