Let's face it, development has gotten easier throughout the past few years. Gone are the days where you'd have to write all of your code through terminal on your favorite modded vim or emacs editor. Every language almost has an IDE built for it, and at times, we've grown to live with it. Yet even with these luxuries, there are still parts of the development process that can act as bottlenecks for those who rapidly bust out updates on a periodic basis. Thankfully, with the help of some tools crafted for such issues, we can reduce those bottlenecks and continue developing at a fast pace.

You don't want to needlessly burden them with too many interactions, buttons, or text. These days, people expect things to just work, and on top of that, they want it to be easy to use.
