I just discovered the “markup” ability by using Asana on my iPad. I can review uploaded design images on a task, and enter into “markup” mode. That’s awesome!
The only request I have is a smaller / thinner pen. The smallest pen size is honestly still too thick to be legible. I don’t know if there’s an issue with the thickness value you’ve designed into the feature, or if creating one more pen size would solve it. It needs to be two or three points smaller.
I have an image that shows Asana small pen size (in green) versus the Apple Pen’s thinnest line (in red). I need something about this thin to really mark things up legibly. The ability to markup is a great discovery for me, and I really appreciate that feature now that I know I can do that!
