Please allow a possibility to bring the New Tab button on the top of the list, when using the vertical tabs.
Now it is at the very bottom of the list and it is almost useless! When having lots of open tabs, it is very awkward to reach, it involves a long distance with the mouse and also quite some scrolling.
Alternatively, allow a “New Tab” button to be place on the bookmarks bar, perhaps next to the “New Tab Group”
