The number of columns can be increased up to 255, but I don't believe the
default can be changed.
You can select multiple columns at one time and then use the insert Columns
menu item to add that number of columns.
== Click on the narrow gray bar at the top of the column and while holding
down the mouse button drag left or right to select multiple columns
== Select Insert Columns from the menu
