<p>The line numbers are generated by the Scintilla editing widget Geany uses, so it might need to be changed there unless the plugin hid the Scintilla line number margin, and used one of the text ones to show its own generated line numbers, and then it needs to hook into all the messages where line numbers change.</p>
<p>In other words the plugin would have to turn off the line number margin code in Scintilla and re-create it itself because there is no line number generation code in Geany.</p>
