Passive skill planner (in-game)

I know you plan on making a planner once the tree is in less flux. I've also seen plans for things you do on the website affecting your character, such as trades.

Being able to 'save' a planned out skill tree to your account(or to a character on your account) and having the nodes slightly highlighted or colored in game so you can see where you planned using the website tool would be a nice feature.

Not really an issue for me, or anyone else with dual monitors, but for someone who would constantly have to alt tab, it would make planning much easier.
