Saola-Animate can create breakpoints right on the Canvas rulers.
but there seems no extra place to enlarge the font size of the scale on Canvas ruler.
So the font size of the Canvas ruler’s scale seems must be almost invisible small.
Question ) Is there a way to modify or enlarge the font size of Canvas ruler?
Suggestion ) Perhaps you can consider
to show a tooltip to help user to see the scale number on Canvas ruler
which is pointed by user’s mouse cursor.
or show the scale number on a status bar
(or something like that) to help user to see what scale is now.
