Again, that isn't the point. I can edit code, that's not hard. However, being able to create new tabs, and not only create the tabs, but set permissions, and give them children with a simple UI is very handy. I've saved a bunch of time already by being able to do the above with 5-10 clicks, instead of having to edit PHP and CSS files for each change - I don't have to worry about bugs in my code either.
The setup I have now with FusionMenu works great and I'm perfectly happy with it, but I would expect the next major update IPS makes to include this feature.
