Passive Skill Tree Road-map Function?

Hey, So I don't know if I'm making a duplicate post here so please be gentle.

So I'm sitting here in my first hardcore league as I've been hiding in standard like a coward/noob, and I'm just winging it on my passive tree. I noticed that the only interaction we really have with the nodes is left-clicks for investment and refunding. I'm curious if Implementing a right-click function or a ctrl+left-click function to highlight a road-map for future passive investment/edits would be of interest.

To take it a step further we could take those third-party passive skill tree planners and upload a pre-made road-map.

Having to reference back to passive skill tree planners can get a bit cumbersome, I feel it would be convenient to implement such a system in game. Much like shop tabs got consolidated from the forums to the in game stash tab system.

Thoughts? Objections?... Memes?......... Roasts?

why not
