Title: Add a multi column container

This container can store an arbitrary amount of other columns
but only display a fixed amount of those columns, this is useful
when you have an unlimited number of columns but only want to display
a fixed amount of them to the user (it also provides visibility
notifications when there are more columns to be displayed on the
left or right of the currently active columns).
