When working with the detail pane of the contract on the right side of the screen, certain tabs are irrelevant for some companies. Making the extent of all the tabs cumbursome to work with but you are also loosing oversight of what you should look at and what not.
Having the option to specify in the settings which tabs should always be visible by default for users and which don't need to be visible, would be interesting. You now have the option to change it individually, but you should be able to set it up for all users as an Admin.
