This is something I’m constantly running against despite using Props ever since it was released.
Personally, I don’t think it makes any sense to double-click on the prop values and have it turn into a rename of the prop. I want to edit the values.
I also understand there’s a button that appears on hover, but this could all be made more intuitive by turning the entire container into a shortcut.
This behavior already exists within Figma. It is shown when you’re editing layers inside a component.
