Fixing Material Design
If Google asked me to enhance the Inbox mobile app I’d revisit some principles of Material Design as well with a more NUI (Natural User Interface) approach: no hamburger menu (settings under profile dropdown), important buttons to the top (the “+” for instance), better multiple accounts switching, one-step pinning (the tiny blue square), 4-dots menu for folders, unread/pinned info, pinned messages to top, way less hidden features.
A more direct design language
What if the full potential of the user interface was really and immediately at your fingertips? That’s the leading principle for the custom design language I used for this redesign. In addition I focused on making the emails look like real objects in a defined space and the text bigger considering the dimensional range of the target devices.
