New Summoner Spell Suggestion - "Analyze"
Target enemy champion from global range and debuff him with "Analysis" to see the current state of his cooldowns and also gain vision of him for 5 seconds. During Analysis the affected champion will have 4 buffs (in the window that usually shows enemy champion, below items section) and they will be shown as QWER with circular clock arrows indicating their current cooldown. Also if the champion is invisible, you and your allies will be able to see where he is, but not attack him, unless you have true sight.
