These are some of my preferred Workday Studio preference changes I've made over the years.

Navigation: Window > Preferences

XML > XML Files > Editor

• Uncheck "Format Comments"
  • It is incredibly frustrating when formatting an XSLT comment destroyes the format and readability of a long comment block

Fonts

• Search "font" at the top of Preferences and replace everything with your font of choice.

General > Workday > Deployment

• Check "Include source code in deployed CLAR"

General > Editors > Text Editors

• Line spacing (extra % of font height): 25
• Check "Enable word wrap when opening an editor"
• Check "Show line numbers"

XML > XML Files > Editor > Syntax Coloring

• "Comment Content" and "Comment Delimiters": Custom dark orange color to stand out from other text
• "Tag Delimiters" and "Tag Names": Change to a pink or purple to differentiate them from XSLT tags
