Rek'Sai Cooldown suggestion

So after playing a few games as rek'sai, I couldn't help but notice that her cooldowns between forms don't show when in the other form. I play rengar a lot and I really like how when he has 5 stacks of his passive you can still see the cooldown of the normal ability. Not sure if this shows on other characters that have two forms (elise, nidalee, jayce) but I would like to see this added.
