关于“在定制里找不到相关的按钮”，其实在标签页最右侧哦，见开发者提供的“屏幕截图”，另外，选择“定制工具栏”后，可以拖拽相关图标到你想要的位置。最后，希望开发者可以让这个图标中的字母，加粗加大一些。——还有，希望开发者增加“关闭左侧标签页”设置，否则会很鸡肋。

这个插件用了4-5年了，感觉非常方便。

Hell, yessssssssssssss.
加个快捷键简直完美~

在定制里找不到相关的按钮

One star as it's dangerous in the current version when you have Simple Tab Groups installed. If you have installed Simple Tab Groups, all tabs in other groups will be deleted. This is dangerous. I also will create a ticket on Github for it.
