Change Unity dash overlay size in Ubuntu

Hey guys, Unity dash is a richly built, cool looking and a very fast desktop and online search bar for Ubuntu unity desktops and notebooks. But the size of dash is "half-way"(800x600ish) for some users and full screen for some users by default. For screens that are larger than a standard netbook, "half-way" is the way it is intended to be. This is called "desktop mode". There is another mode called "netbook mode", that opens dash in full screen size. Mine was "netbook mode". by default, but one day when I had to add some app by dragging and dropping into some another application, I was unable to do it in "netbook mode". Then I changed it into "desktop mode" and  continued my work. So, I thought sharing this trick will help somebody with the same need or who are trying to bring a little change in the way they look their dash everyday!

Steps:

There are two ways in which we can achieve this:

Method 1(Using Ubuntu tweak software):

Open Ubuntu tweak software, search for dash in search box, you will get an option called unity. Click on it and in there you will find an option "dash size", change it according to your need! cheers! Isn't this simple? That's what great about open source, we can change our Linux box, the way we want! Screen shot below:

Method 2(Using commands):

Open your terminal, for "desktop mode", type:

gsettings set com.canonical.Unity form-factor 'Desktop'

for "notebook mode", type:

gsettings set com.canonical.Unity form-factor 'Automatic'

or

gsettings set com.canonical.Unity form-factor 'Netbook'
