Is it possible to do version control or change log?

[eexpss]

I think about this. I fell very dangerous when modify my file.

1. The files had been packed as zip, not possible do version control directly.

2. Need a backup file or Save as a file each time. After unzip and compare, It seems the most possible is to `diff` Document.xml, but need fetch out those changes and write it to the log leading with "Object name". Phrase XML is simple.

3. If the "Undo" can include placement changes, Maybe create a "change log" from undo list. <- most correct in principle

4. Let user write a change log manually and saved in the file. sad one.
