Secondary Slot Runes Cooldown/Stacks

Hello, Since recently they added to the *Hunter runes a tooltip showing which bounty you have collected and which is remaining, I was thinking about the other secondary (not Keystones) runes with cooldowns or stacks that would be nice to have in check. One common thought was surely "Riot could add the bounty list to the hunter runes, but then you wouldn't see the players' skill/talent remembering who they have or don't have killed." And they added it to simplify the experience.

Currently it would be nice to see as buff/debuff/cooldown: Legends - stacks Coup de Grace - buff duration Last Stand - stacks (varying based on health) Cheap Shot - cooldown Taste of Blood - cooldown Sudden Impact - cooldown and duration (the lethality/magic pen buff duration) Nullifying Orb - cooldown Manaflow Band - cooldown Scorch - cooldown Unflinching - duration Demolish - cooldown Iron Skin/Magic Shell - duration Overgrowth - countdown Second Wind - duration

What do you think about it?
