It is possible to hide revision bars by following these steps:
- Go into System;
- Settings;
- Documents → General;
- Select the option "Allow removal of Revision Bars".
Once this is selected, in Editor, click on the delta associated with the revision bar that you wish to hide, and you will see the "Hide Revision Bar" button. Once selected and saved the revision bar will appear grey in editor but will not be visible to the reader nor in the PDF.
Note: revision bars can only be removed for the full text section, not per revision bars.
