Tab List Board 作者: Azicore

The Tab List Board opens by add-on icon or F1 key (configurable), and it shows you a list of all opened tabs in the window. You can create a tab list and classify tabs, or can sort tabs and tab lists easily on this board. If you click a tab, you can switch to the tab. A green tab is a tab you were browsing just before, and F1 key (configurable) lets you back to the tab.

A sidebar will open by Ctrl+F1 (configurable) and it shows a list of tabs which belong to the same tab list as the current tab. This helps you to switch tabs more.

I made this add-on for people who think it is difficult to switch tabs by tabbar because of many flooded tabs.
