Non-Path-Restricted Planning mode
I'd love to see a mode where you can click on nodes anywhere in the tree, and not require a path to get to them. Ideally this would also have a way to highlight them different colors. Just as a sort of way to identify which nodes I really want to plan towards, and which ones would be good, but not required, etc.
The node power / power report should fullfill your needs.

Oh! Ok. Sorry about that then. Thanks!
I'm not entirely sure what you mean, actually, I can't figure out how to select/highlight any nodes without actually routing a path to them. Maybe I wasn't entirely clear, I'm trying to mark all the individual nodes I want to eventually path to, but don't know the best pathing for them yet.
Has this been entirely dropped? I mean the Power Nodes have nothing to do with this feature request as it doesn't allow you to individually highlight nodes (or wheels) across the Tree.
This is easily my most wanted feature. It's much easier to make a build from the edge-nodes in than it is from the starting location out. Would also mean I don't need have to add a dummy amulet just to have an anoint. Or allocate passives within Thread of Hope / Intuitive Leap / etc range without actually having add those items to my build.
