There are many operations available in the UI, and some operations can be accomplished in several different ways, so it’s likely you’ll want to hide those ways that won’t be used. For a given workflow and task, consider the following:
What types of items will users work with? Because each view in the Browse tab supports a distinct group of items, you can remove any views that users don’t need to see. Also, modify the Search tab to make sure the item types you want work with are visible and remove any others.
What actions will users perform with those items? The actions users will perform determine the tabs they need to use. If users are tasked with creating items, there’s no need to display the Search tab, Project tab, or Multi Edit tab. For users who are editing items in bulk, you might want to keep several tabs present, so they have options for locating the items they will modify. Users who are approving item changes, for example, are likely to use the Project tab and/or Search tab, but not the Multi Edit tab or the Browse tab.
How will users work with item properties? Most items come with many properties. If some properties aren’t useful, remove them from the UI as described in Controlling the Properties in the Details Pane.
