Feature request: Fixed number of columns, possibly exceeding window width
iTerm2 currently changes the number of columns dynamically with the window width: resizing the window changes the number of columns.
This is usually the way it should be. But occasionally, I'd like to have a fixed number of columns, independent of the window size.
I therefore propose a new feature: allow the number of columns to be fixed.
That option allows us to set an arbitrary number of columns. If the window is narrower, a horizontal scrollbar appears. If the window is wider, a border could appear after the last column. Either way, resizing the window in this mode wouldn't change / rearrange its content.
