It has lots of controls for how it is displayed, including the ability to only show top level nodes (ones that aren’t in frames), and all colours are customizable.
It can also be used to navigate the node tree using these controls:
Clicking and dragging on the mini-map pans the view
Double-clicking the mini-map centres the view to fit all nodes in the tree
Clicking on a single node will centre on that node.
You can get it here for free:
One thing to bear in mind is that on very large node trees (400 nodes +) it can start to slow down the 2d viewport, especially while moving/editing nodes, though this won’t affect most people.
It can also function as the world’s worst and only node based pixel art editor!
After migrating from 3.4 to 3.6 while addon active no any minimap visible in shader editor. It’s only on my side i suppose then?
edit: sorry for inconvenience - all works as intended!
