Some of the fields are not listed in the main view and some that are listed I don’t need. How do I adjust the view so that only needed set of fields is visible?

Right click on any of the column names, this will allow you to quickly enable or disable fields from the view. If you need to alter a significant number of fields at once, choose the Customize option. To reorder columns, click on any of them and drag it to another location within the table.
