I'm sure you've seen this before, you hit enter, 2 trees get selected, you've just harvested one, and you have a 50/50 chance to pick the right one to harvest the other.
Why is this a matter of odds?
It's good that things glow when they are in selecting range. They don't have to still glow once the menue is up. What if ONLY the item that your selecting from the menue was highlighted once you've hit enter. That way you can see that the tree that's lit up, is the one on the right, and you want the OTHER tree.
