Keeps a spare blank tab open to switch to in case a new tab needed
You know how Vivaldi is slow to create a new tab? Especially when you have a lot of tabs open. This extension keeps a new tab already open waiting for you at the end for the tab bar. To use Ctrl/Cmd+T to switch to it go to "Preferences" -> "Keyboard" -> "Tab", remove "Ctrl/Cmd+T" from "New Tab" and assign it to "Switch to the Last Tab".
