UPVOTE DISPLAY ON ARTICLES

THE PROBLEM
Very often when i upvote on members contents, i really don't know when the upvote is casted until i try upvoting the content again then it will notified me as a warning that removing my upvote will remove the reward given to such contents. This really most times delay me from visiting other posts and it becomes very annoying when bad network sets in
SUGGESTION
I do visit Facebook and i always like using the like button. On Facebook, once you click the like button, it displays to you that you have liked such post

Now it also have where you will click to view all the people that liked the post too.

Steemit should employ similar or same display partern. More of the screen shots are below
BENEFIT
By indicating that you have upvoted a post by way of writing your name on the upvote button or displaying your picture on the upvote button, the user interface will look very much enhanced and it will save alot of stress to upvoters who contemplate on whether they have upvoted a post or not
Conclusion
This feature will no doubt clear doubts and give an excellent user friendly platform on steemit
