Well, the problem with that is that the arrows actually point out on-map actions. It won't just be jumping. There's things like hidden chests/passages, double-jump areas, climbing cliff parts to name a few. I liked the arrows as a general, consistent guide to things that can be effected.
I guess I could have them be on/off toggleable, but considering you need to know where things can be effected in order to progress, I'm not sure it's worth it.
