Thanks for plugin - very-very cool.
But can You add ability to change F1 hotkey to user defined hotkey. Developing in cloud IDE need that hotkey for their options.

I use it all the time. i can see in a glance which tab is parent of another. and I can jump from the first to the last in a click, evne if i have more than 100 tabs opened.

After using it, now I need this in every browser I use.
Side note: If someone wants to hide upper tabs, they can do so using custom css or install addons.mozilla.org/en-US/firefox/addon/toggle-native-tab-bar/
