Pivot Table

The Pivot table Fields sidebar is super large and I am having problems reading what is in Filters, Rows, Values and Columns.  I tired to figure out how to zoom out to make the sidebar info smaller to show more of it but Could not find where this option is.

In addition, when I selected the date, the pivot table added columns for the years, quarters and dates.  I want the pivot table to have the + or - sign to expand or shrink the view in 1 column but have not been able to find ho to correct this option either.

Thank you in advance for any assistance that you can provide.
