Preserving sequence of operations performed in a document/graphic for later usage

When we create an object (a drawing made of various components) - it is difficult to remember the sequence in which the drawing was drawn. Infact, if it a tabular format sequence (like Sudoko) where the sequence is important it is difficult to show the sequence of operations to a user who opens the document later.

I was in a class where the Professor had described the method to solve a problem by Linear Programming (Simplex method) [Simplex involves a table to be filled up with data]. I had copied notes from the board but when I went home it took me long to imagine the sequence in which it was solved. I wish if there was a method that could indicate the sequence in which the notes were written. Could not find a prior solution for the same.

The concept of the idea is denoting the sequence of operations (be it text or image or handwritten notes) to the user (for later use). It would insert superscript numeric numbers so as to denote the sequence. When a document or image is reopened later a user may easily recall the sequence in which he had typed or drawn the object. This idea if implemented could help in: Understanding the sequence of operations while drawing or writing where the order of sequence matters.

DETAILED DESCRIPTION:

Usage of superscript numeral text to denote the sequence. That text would be conditional (can be made toggled between show/hide) http://en.wikipedia.org/wiki/Conditional_text For Text: -Implementation of this idea for text should be easy via adding "numeral superscript" to the text. -The numeral superscript would be something like a "n+" operator which auto increments by 1. -At logical breaks, the n+ could be added as a superscript to the text when the tracking of order sequence is ON. -The n+ could be a part of a conditional text that could be hidden or displayed when required. For Graphics: -Implementation of this idea for graphics too could be implemented via "numeral superscript" to the graphic-part. -The numeral superscript would be something like a "n+" operator which auto increments by 1. -At logical breaks, the n+ could be added as a superscript to the graphic-part when the tracking of order sequence is ON. -The n+ could be a part of a conditional text that could be hidden or displayed when required.
