Please create the ability to duplicate components (not just instances).
I need to create a set of similar components, and creating them from scratch each time will take a while, is subject to error, and leaves me looking for a “duplicate” feature.
Thanks for receiving! 
Looking forward to this, it’s a pain having to completely recreate a component from scratch each time.
In the interim, you can work around this by editing the component, copying the parent div, moving it outside the component, pasting it into the structure panel, applying your changes, and then converting it back to a component.
That could also mean you should use component variants and not similar components.
