Hello !
this is not to mention a bug but more of a question and if it does not exist yet a suggestion.
It is possible at this stage to draw a straight line with the pen tool then use some filter or options to create a Zig Zag from it ?
Like one would do to make waves or to illustrate waters flowing/moving.
i know it was possible with Ai but not yet tried to create it with Affinity Designer (Beta or Retail), so i ask.
if it is not implemented (such a filter or a straight function to make zik zag of vector lines and smooth them or sharp them) then i would ask it (for both Windows and MacOS) because it is helpful and time saving and very useful for logos design.
Blessings !
