If you're a Gmail users who's frustrated with the cluttered interface, I have a simple and free tool for you. It's a free Chrome extension, aptly named Simplify. The extension removes all the visual clutter within Gmail, including the sidebar and excess sidebars. It makes the gmail experience you crave and wish Google would have made in the first place.
Need a Google Drive version of this extension
You can download the extension from the Chrome store for free. I am hoping the next extension Micheal makes is one to declutter Google Drive. I want Drive more focused on the files and less about everything else going on with the interface. I am thinking Dropbox but slightly more minimal.
