Ubuntu Tweak is just what we need. Let's install it.
1. Open a TERMINAL window
2. Type the following in the TERMINAL window;
sudo add-apt-repository ppa:tualatrix/ppa (Hit Enter)
sudo apt-get update (Hit Enter)
sudo apt-get install ubuntu-tweak (Hit Enter)
ubuntu-tweak (Hit Enter)
3. That last one launches Ubuntu Tweak.
4. Done. (there are too many options to explain them all. See Screen shots)
TIPS:
You can find the Ubuntu Tweaks program under the SYSTEM filter in the DASH or by doing a search for ubuntu tweak in the DASH SEARCH.
On the TWEAKS tab there is an option for UNITY. This is where you tweak your UNITY LAUNCHER BAR (left side in screen shots), your DASH and the UNITY TOP PANEL. I like to set my Unity Launcher Icon Size to 32 so I can see more icons on it and I like my Dash Size set to Netbook which makes it full screen for some reason.
