For me it is one of the standout features of Elements from a usability perspective.
Agreed, I LOVE the node browser 
On watching your videos I really couldn’t understand why you were going there so often - but it soon became clear. Whatever you do with docs or tutorials you need to make sure it’s not seen as intimidating. It looks complicated but in practice it’s a breeze.
That’s great feedback and really good to know.
While we are talking about the awesome node browser, there is one small improvement I would like to see.
In DARK mode I think the icons are to dark making them harder to see. It does reduce the visual clutter by having them pop a lot less. But personally I would prefer them to be brighter.
