The bulk of the upgrades this year centered on Google+.
1. Change from one- to multi-column layouts by clicking on the More tab. Three-column layout exists but only for the largest of resolution displays. If you want to take a peek at it, just reduce your zoom on the page. The design is fully mobile responsive.
2. Shift+L will rapidly refresh the stream bringing you to the top and the new posts if you don’t want to click the button. There’s currently no way to return to auto-refreshing of the page.
3. Infographics will display in a nearly useful size at full length in the new layout. Estimated dimensions 503×930 for desktop viewing. An influx of infographic posts is likely. Keep an eye on ensuring readability.
4. Find an assortment of additional information related to each post by clicking on its “Shared Publicly” or “Shared Privately” link right under the authors name to flip the card over.
