How do I aim a Korok Leaf?

Answer

I took the crazy idea of trying to throw the leaf using the 'RB' throw button, and it actually did not throw the leaf like I wanted! Instead, it blew in my currently facing direction with that familiar reticle.

Etc.

So that seems to be the answer, and in case you actually wanted to throw your leaf, well, I guess I don't know if you can do that in the game currently. :P

This wasn't a huge issue, but wanted to post in case anyone else was searching for the answer by chance. I was a bit too protective of my items in the beginning of the game, coupled with the durability factor, and didn't want to lose my leaf! Then I found it's a common and replenishable item from destroying trees, and I'm not even sure if it has limited durability to worry about.
