OrganicView for Google Docs
More About OrganicView
OrganicView by Writora works with any Google Doc you can edit. When you click Add-ons > OrganicView > Create OrganicView, Writora creates a view showing every change to every snapshot of that Google Doc. OrganicView allows you to filter changes by editor or snapshot, and to select any change to remove or restore. After you select changes, you can preview the selected changes, and then commit the selected changes to create an entirely new snapshot of the Google Doc.
Collaborative document editing just gained a brand new tool, making it even easier to create the best document from all of the changes made.
