I would put 5 white stars that transformed to 1,2,3,4 or 5 yellow stars like giving feedback on ebay !!!
1 star 20% vote power
2 stars 40% vote power
3 stars 60% vote power
4 stars 80% vote power
5 stars 100% voting power
or you could even use the steem logo instead of the stars! like on slack with :steem: Add reaction
Here is a visualization of my idea...

Right click on the image and click "View Image" to see it in the original size....
I don't know why it appears now smaller on the response than before(?)
not to mention that giving 5 "steems" reminds us our historical +5 meme :)
I agree that looks nice... for people with a mouse. We will need to come up with a solution for people with fat fingers.
Great idea!
Has become natural @liondani
what happened to this suggestion?
