Hi, Abanob –
I understand your problem – but I think it would be worth it to try. Everything for Elementor should be in the same place. This is logical. It also helps to keep the admin menu clear. A big site for a client can have many entries on the Admin menu – so an exclusive entry for Premium Addons is using unnecessary space.
Premium Addons is great. I always install the Pro version for all of my sites!
