There is lots of interest in wanting to draw in Zinnia on a Mac, which is an exciting concept! Currently, our drawing tools are available on iPads and iPhones, however we are exploring how to bring this functionality to Macs, despite the lack of finger or stylus input.
We always enjoy receiving feedback from our community and appreciate suggestions to improve your journaling experience. Drawing on Mac would indeed be an amazing addition, and we aim to implement it as soon as it is feasible from a technical standpoint.
Our commitment to regular updates and improvements is fueled by your ideas. Check out this article for how to get your ideas to us: Request A New Zinnia Feature.
