I came across Simplify a few days ago upon reading an article on Fast Company. It is a Chrome extension that helps clean up your Gmail interface. Instead of looking at unnecessary features, buttons and logos, Simplify helps clean up the interface to make it look better. Here is what Gmail normally looks

Here is how it looks on mine

If you click on the icon on the top left, the interface will be even more minimalist

My experience with the extension has been very pleasant so far. The mailbox looks a lot less busy with the removal of features that I haven’t used much or at all. Plus, whenever you have inbound emails, the layout won’t look to command attention as much as the original ordinary Gmail outlook, as you can see below

Another nice thing about Simplify is that it is not serving ads or collecting any analytics, in addition to being free.
If you like a minimalist design and a cool free product, give it a try and show the creator some appreciation by endorsing him like I am doing now.
