Scroll long Status Bar

[barsdeveloper]

Sometimes the Status Bar (the blue bar underneath) can be quite loaded with information especially when a lot of extensions are installed. Sometimes, on some screens, those information can take more horizontal space than the width of the monitor. I would suggest to add the horizontal scroll functionality to the Status Bar exactly how there is for the tabs bar. When there are a lot of tabs open that exceed the space, the user can still see all the tabs by scrolling with the mouse button. It would be nice to have the same for the Status Bar.
