The deletion is triggered by pressing the <LEFT> arrow. Your suggestion
would make the point move right. This is not optimal either.

Maybe the other way is better. Since column creation is triggered by
pressing <RIGHT> arrow, we might create it to the right of the current
column, and point would move into it.

WDYT?
