I love the smooth connectivity between my iPads, macbook and iMac with Safari... and its only gotten better with ios8 and Yosemite. However... I just can't switch! I customarily have 40-ish tabs open in my browser (iMac) With vertical tabs, this is super easy to keep organized and instantly switch to any tab I want. There's nothing even close with Safari for 1-click instant tab access :-( Especially with todays great wide screen displays, using the side tabs is a far better use of otherwise unused website real estate- Also, besides just being able to see all the tabs ALL the time, they are easier to identify. Each tab has an icon displayed for easier recognition. Conversely, Safari tabs may or may not have anything useful displayed depending on the page displayed... it MIGHT be the website title, but it might also be an obscure few words from the link. Im dying to use Safaris OTHER features, but this BIG lacking one is killing me... is there another way?
