In SF we discussed a strategy for compartmentalizing our codemirror editor logic in terms of HoCs. This is the strategy we use for breakpoints and highlighted lines

Tasks:

• Breakpoints file
• Highlight Lines file
• Debug Line pr
• preview popup pr
• Text gist
• HighlightLine gist
• Conditional BP Panel gist
• Gutter Menu might be nice too

Rationale:

This will help untangle some logic and improve readability and testing.
