group add button should have left border and the x padding should be smaller, try 3px
Added a left border to the "+" button and reduced its horizontal padding to 3px using inline styles. The button now appears more compact and visually connected to the group tabs while remaining clearly separated on the right side.
reduce the x padding of group button to 6px. make the group buttons container x scrollable
Reduced the group button horizontal padding to 6px using inline styles and added overflow-x-auto to the group tabs container to make it horizontally scrollable. Also added shrink-0 to both group buttons and the "+" button to prevent them from shrinking when the container overflows.
group tabs container is x scrollable but the scrollbar must be hidden;
the "+" button is not part of the scrollable area, when scrolling the group tabs, it always remains rightmost position.
