This is definitely not a big deal, and maybe it is only personal.
I keep reaching for the +
sign to add new elements, despite them not being there. It is kind of a natural place to expect elements and I need to get used to not clicking it.
But how 'bout actually adding a “Element” part there, which opens the element pane when clicked, much like how the “How would you like to start” screen opens the Templates tab when “Use template” is clicked?
It might reduce some micro stresses for the new users. And also apparently for some more experienced ones.
