I posted question How to scroll Panel tool bar?

There is no way to scroll Panel too bar. (now)
I need to click on the icon and close it, I can indeed see the hidden icon without having to scroll.
However, the farther away the icon is, the more times I have to close it. I will have to click on the icon to undo this. There are seven in all.
It's a nerve-wracking and frustrating task for tablet and mouse users to adjust the mouse cursor to a small icon and click it, and it's tiring.
So I think the scrolling method in the blender is more convenient for mouse and tablet use.
I just noticed that the icons are hard to see and at the same time, it's hard to know what state they are in.
I suggest that scrolling would be the best solution.
