Creating a new interface isn’t intuitive - you have to click on the interfaces button from within the base instead of using the standard + button in the interface area. It would be much nicer to have a more intuitive and easy way to create a new interface. Hope my drawings in my screenshots are up to snuff, haha.
I would also like to request to be able to duplicate Interfaces - aka interface groups. It is nice to be able to duplicate the individual interfaces within an Interface Group, but being able to duplicate the whole thing for users is essential.
