Sometimes in SharePoint list page we might want to display more than the default size of view visible. The default number of view display is 3.

So what if if we need to display four.

Here is how you can do it

• Edit the default view page let’s say Allitems.aspx

  

• It brings the page with web part zones

  

   

• Edit the Script Editor Web-part and add following  a script

  

   
  ExecuteOrDelayUntilScriptLoaded(overrideSurfacePivotCount, ‘clienttemplates.js’);function overrideSurfacePivotCount() {
  ClientPivotControl.prototype.SurfacedPivotCount = 4;
  };

You can increase the Pivot-count to the number of view you like to have.

Now save the page and you should see the fourth view in the default page of  the list.

This will only work in SharePoint 2013 or other on premise SharePoint but it will not work in SharePoint Online.
