Request: To add a margin that can display a custom text value for each line. Each line of text has an associated 'margin text' value that can be displayed along side the line.
Motivation: I would like to use Scintilla to display a portion of a document with custom line numbers. The line number of line displayed does not correspond to the actual line number in the original document.
This could also be used for various other purposes (including a date/time column).
