The claim in the title may appear bold, but I think one can argue this would be an improvement.
- Interact can do things the coupler cannot. So when I open the coupler menu, and realize I want to, lets say, change visibility, I have to exit the coupler, and the interact (on mobile this feels as if it would even require to exit edit mode).
- You are forced to learn two concepts and their distinct user experiences and capabilities. This would only be justified if there is a good reason for it, which I fail to see.
I am aware that this merger may have serious ramifications and would require some thought.
Still, I would be interested in how everybody feels about this.
