Issues

export the extra column for the letter grade only, not the combination of letter and percentage

Letter Grade mode does not work with Pass/No Pass

Letter Grades, Weighted Categories -- course grade calculation boundary annomalies

Allow students to see Xtra Credit scores in green (and the item text in green too, if possible) & see not Include in grade scores in gray (and the item text in gray too, if possible)

Grade import history needs to differentiate (% to Letter) and (Letter to Letter) "conversion"

gb2-import structure - import gives blank, grey screen if there is a problem w/imported spreadsheet

Optimize method convertPercentageToLetterGrade(...) in GradeCalculationsOOImpl.java

Letter grade scale is not editable & Grade Scale is not working properly
