You currently have to switch between the objects. We are discussing multi object editing. But there are some downsides that comes with it. We are trying to figure out an intuitive and "foolproof" way to overcome these. In this context, also evaluating auto-blending. So select to objects, click auto-blend and the "edged" get autoblended for a smooth transition. Enhancing the Mesh Geometry Manipulation tools is on our "long-time" ToDo list. Extrude, Pinch, Push, Smooth will for sure be not the end of the road. Currently focussing on polishing the shaders in terms of quality, flexibility and performance. Day 1 "Patch" already waiting to be submitted.
