What a waste of fossil fuel energy!
What a waste of laptop battery!
It can be really hard to make software efficient, sometimes there are easy wins.. seems odd to not just do it.
An insert or delete from (e.g.) a rope is very cheap and as they are immutable can make some other features very easy... saves copying megabytes...
Worst case scenario for a plain array is if you insert to the front of the array where it has to shift everything down one. But even if the file is on the order of several megabytes, this will still finish in milliseconds at most and the typist won't notice it.
