Move Your Tabs to the Side in Google Chrome/ium for useful widescreen browsing.
Vertical Tabs is a handy and simple add-on for your Google Chrome/ium which, as it's name suggests, lets you browse your tabs… vertically!
Simply use the command-line flag:
C:\Users\Troy\AppData\Local\Google\Chrome\Application\chrome.exe --enable-vertical-tabs
If you start Chrome/ium with that command, you can right click on the tab bar and check "Use side tabs" to enable it.
