When I use Google Docs, I often find myself wondering “What did this line of text say before it was changed?” But there is no easy way to answer that question.
Ideally I would like to point to any given word, phrase, sentence or paragraph, and quickly get a history of just that portion of the text. What was the sequence of changes that produced this particular sentence? When was it last changed? Who changed it?
It would very useful to have a “local change search” feature, which would give me that kind of local history of changes to a document. All the information needed to implement such a thing may very well already be contained in Google Doc’s Version history.
Alas, as an end user, you only have access to Version history for the entire document. There are no tools available to you to forensically examine selected portions of successive versions of that history.
I wonder how difficult it would be to implement local change search. I’m sure a lot of people would find it useful.
