Today I install synapse in ubuntu. It is used for easy searching. Actually, in GNOME searching is not very easy. Every time, when I want to search any software, Then I have to click on main menu first. So, Amrit told me about Synapse and I install it. And set shortcut for this. It will search software as well as files and folders.
After that he show me his terminal because he was using Z-shell and I like zsh appearance. So, I install only zsh and after that I download its oh-my-zsh theme and add it. Now shell looks nice.
