Triangle ruler
Many users asked for a ruler but in my opinion it makes more sense to add a triangle ruler as a new funktion, because then you can't only measure lenghts, but also measure angles and draw straight.
Especially in math or physics classes, you often have to measure or draw angles.
And putting your physical triangle ruler on the iPad isn't a nice longterm solution, is it?
Therefore I would be happy about a triangle ruler funktion in GoodNotes 5 :D.

This would really be a good thing.
The triangle ruler would need the ability to
 can be rotated
 can be adjusted to the scaled
 can be fixed in size when rotating (images and stickers can not be fixed)Furthermore we could use this as a mathematical compass (german: Zirkel). If we could choose a radius on the scale of the triangle to draw a line, we could rotate the triangle ruler and draw circles.
Would be super nice for everything regarding geometry.
Pleeeeeease! :)

GoodNotes needs a triangle ruler for the home schooling! An example for this function you can find in the APP "Digitales Schulbuch" (GooglePlay)

Goodnotes needs a triangle ruler and an linear feature
