Hi all.
I usually limit line length by 80 in my own projects, but in Geany 100 symbols is recommended. If the long line marker position preference was project-specific, I would not need to change it in the Preferences dialog every time I switch between Geany sources and one of my projects.
If making this preference project-specific makes sense for you, I can spend some time to implement it. Otherwise, I will just ignore the issue (I don't consider it important).
Best regards, Eugene.
