Key combination to draw lines on multiples of 15 degrees (15°/30°/45°/60°/75°/90°...)

[anonymous]

Could you add a key combination or modifier (Alt + Shift?) to the Draw nodes (A) tool that allows you draw only new segments that are X degrees apart from the previous segment, where X is a multiple of 15?

This would allow the creation of geometrically precise areas in an easy way. Such functionality is available on all the vector graphics applications: Inkscape, Blender, Gimp (in its vector parts), ecc.
