It really would be, if you have a farming script with say 100 village coordinates, and as always happens someone nobles one of your barbs, then you have to search all the way through those coordinates to edit out the ones you don't want. It is so awkward to try and do it in that tiny field that I actually copy and paste the whole script to notepad so that I can work with it.
Perhaps the field could appear the same size but have a link to turn it into a much larger box. Same way you can make the message box larger or smaller.
