Agree that decisions/designs are important.

However, not everything can be well designed at the beginning. Skills of editing will affect efficiency, especially in a try-and-error loop of new ideas/approaches, where only a rough design exists.

Besides, some niche editing tasks (which may involve column editing, macro recording then batched execution, regex based operation, encoding transformation etc.) may otherwise require writing awk/sed or even perl/python scripts as subprojects to achieve, if one does not known the editor well.
