AliasManager allows you to create aliases for your terminal. As a developer today you have to use the terminal a lot. Some commands you are writing over and over again are long and complex, which takes a lot of time from your development. With AliasManager you can write this command once by creating an alias and that's it. Some example aliases might be. "vm" to connect to you vagrant machine. "cu" to update composer. "npmi" to run npm install. I bet you can come up with a lot of commands you can create aliases for.
