This is a very (very) simple UI redesign for the browser version of Gmail. As the brief touched on the current layout of the app works well, so I've opted to only make minimal changes (e.g. location of the "profile", search bar, usage). I've gone for a refresh of the UI to (hopefully) make it more pleasing to the eye, using subtle backgrounds to distinguish each section. Realistically Gmail will follow material design principles which I haven't adhered to. If I revisit this I'd like to experiment with icons in the sidebar menu, and adding back the chat feature which I've left out.
