With the release of elementary OS 0.3, elementary-Tweaks isn't available by default with the " Freya " release.
Although you can install elementary-Tweaks via PPA developed by +Michael Starkweather, for those that are running elementary OS 0.3.
Note: This app is no longer maintained since February 2015. Nevertheless, it works.
- Installing via Terminal. ( Copy and paste the following command lines one by one. )
- sudo add-apt-repository ppa:mpstark/elementary-tweaks-daily
- sudo apt-get update
- sudo apt-get install elementary-tweaks
