Item lock and in game planner

I was wondering if we could get an item lock function. It would also be nice since you are focused on creating the new experience to be more accessible for consoles if we could get more of an in game planner on the passive tree.

Console players don't have the luxury of a second screen, M&K to open up PoB or PoE ninja. At the very least I'd appreciate being able to lay down a sort of ghost path across my passive tree so I know where I initially planned to go instead of constantly recounting how many points I have left.
