Too Long; Didn't Read
Software developers prefer to tweak their tools and operating system to make them more effective and programmer-friendly. I prefer Linux as the OS because of the customizations that can be done on it. I use these tweaks on the daily basis to make my day more productive. Zsh extends [Bourne shell] and has many new features and supports plugins and themes. Vundle is a plugin manager for Vim that lets you use, manage and customize numerous plugins available at your disposal. I love to use Vim for writing code, but I make alterations to it.
