I love Tree-Style Tabs, so had to try this out. For anyone else who had trouble ...

While on the subject of about:flags --

Enable 'Tab Overview' if you have a Mac with a trackpad.

Three finger swipe down shows all of your tabs like expose.

This is my favourite chrome feature! It's so useful that it's convinced me to buy a magic trackpad so I can use this when I'm using the laptop with an external keyboard.

Ctrl + Cmd + t

Thank you!!! I know you're not mean't to put posts like this on HN, but I've been searching for a shortcut like that for a long time! :)

What version has this? I just tried 12, 13 and 14 (Canary) and I don't have that option. I have "Tab Overview" as the first thing in flags. Is this a Windows only thing, perhaps?

In osx I had to do:

     cd /Applications/Google\ Chrome.app/Contents/MacOS
     mv "Google Chrome" "Google Chrome Binary"
     echo '#!/bin/bash
     exec "${0%/*}/Google Chrome Binary" -enable-vertical-tabs "$@"' > "Google Chrome"
     chmod ugo+x "Google Chrome"

This let me start chrome with the "-enable-vertical-tabs" command line switch. Once it was started I needed to right click a tab and choose "Use Side Tabs".

Wouldn't this break after an update?

Probably worth noting that the vertical tab UI you end up with looks pretty weird (on Mac OS, at least), as it's literally just moving the existing tabs over to the side without changing the graphics at all.

to try it out without making it permanent, just open a Terminal window and enter something like this:

  /Applications/Google\ Chrome.app/Contents/MacOS/Google\ Chrome -enable-vertical-tabs

I believe so, I've been using sidetabs since they were released in Canary one year+ ago and I've never figured out how to get it to work on my Mac
