I’m not sure if this is a bug or just a limitation within the app. When I create using the mirror, pattern or radial tool I often want to go in and add more elements to the design. The only tool that lets you draw multiple elements is the pencil tool. The blob brush and the new brush tool (in Beta) don’t allow you to draw more than one element. Imagine I’m drawing a butterfly and want to add more elements to the wings and have them mirror on the other side. I can only do this with the pencil tool. I should be able to use any drawing tool to add more elements within mirror, repeat and radial.
