And yes, the tabs for the node sections are also there in the Composite Nodetrees and Material Node Trees…. but not the case for third party nodetrees.
I guess I just see that one system, the keyboard shortcut from Blender, for the float menu directly under mouse, and the Add menu, have been opted for the tabs system, and only Material nodes have an All Node tab system – which makes sense, so I don’t have to click so many times switching tabs, and just bring them ALL up at once with one mouse or key call. What I would suggest is having a similar system for Compositing and/or third party Animation Nodes.
