@Riot Liss Quality of Life update?

I know this is so small but, is there anyway that E's could have a icon showing how long I have left to press E again? There is so many times I want to fire it off in one direction and run the other to attack someone, but end up ether A) Waiting to long and missing my chance or B) Keep my screen vision on my E travel path and miss other actions.

So would a small icon that times down be too much? I hope I worded that right.
