Not sure if this has been asked or not, is it possible to restrict a user to view a tab? or a component in a tab?
Use-Case
I would like to hide sensitive data from well-wishers of my parish (members list) but allow them to view other tabs (sermons, education, calendar, etc).
Like @George_B said, you can’t hide entire tabs, but if you can get creative with filtering and visibility to only show certain lists or components to certain people.
