Text + Format comparison between two InDesign files
I just want to start eBook creation. I have many different users to write content from manual book. I need files from few users(at least two) to compare them with Text + Format comparison to minimize human errors like spell mistakes, format mistakes etc. I need it as basic feature to me to purchase InDesign as I am really impressed with all other features. But without this comparison feature it is baseless to me. Can you please provide me update is it possible in near future and some solid plans if you are okay.
Or else if you can suggest any workaround for this purpose to me, It would be better too.
