It would be cool if we can view or manipulate rulers without editing codes. Maybe like this:
Something like a widget (a tiny triangle in my case). Operations can be triggered by hovering over or clicking or dragging it, such as displaying/adjusting the width. It can be really useful when we set many rulers and sometimes we need to distinguish them better. It would be even cooler if we can customize colors for each triangle.
FYI, thx!
