Symbol thumb whatever to mark good/helpful answer

[BestNoob]

Hey,

i dont want to advice such crap like EA Answer HQ, Facebook or other sites use, but an option to add a smiley/reaction to a post would be cool
so that i can say "Thank you" without the need to post it, but letting the other guy know that i read his answer

but you can reply with since always already,
this would also be two mouseclicks only

Would be cool though - on Steam, there's a "mark this post as solution" button which pins thaat post to the top of the thread. Pretty useful!
