OMG, this Chrome extension has changed my life, specifically with using Lightning. You know how when you click a link in your email, and that opens another tab with all of your prior Lightning stuff ready to go in yet another Chrome tab? With this extension, Chrome detects that you already have a Salesforce Lightning tab open, and then opens the link in a new Lightning tab in your existing browser tab.
