I spend a significant amount of time during a match trying to find the active node in the AI tree. I spend more time looking for it than anything else during a game. If the node is several layers down then this can take a few clicks and several seconds. Repeat this many times during a game when debugging, and it adds up to a lot of time.
Adding this feature would save so much time for everyone. Please add it. I'm think you would see the number of matches increase a lot after this kind of change.
You could add it as a button in the AI viewer: [jump to active node]
