In DV today, there is the ability to set security on workbooks. It would also be greatly beneficial to have a feature to set security on specific tabs within a workbook. For example, we have a use case today where there is a workbook with 10+ canvases that we would like to open up to a broad community. However, there is 1 tab in which there is confidential info and only part of the community should have visibility. Today, the workaround entails us creating an entirely new workbook just for this one tab. From a development angle we now need to maintain two workbooks rather than one. If we had tab level security this would eliminate the need for users to create additional one off workbooks, furthering the consolidation efforts.
