Scrapping the ‘likes’

I’m sure many will disagree, but I’d love to see the ‘like button’ changed/modified. Personally, I use it as more of a bookmark; that way if I bounce around I can return to a thread and see where I had stopped reading. Sometimes I even catch myself liking a post that states that a family member might be ill or something of that nature; I don’t necessarily like the post, but I know that I’ve read it. I’d much prefer a ‘marked as read’ feature. But that’s just me.
Thank you
