When a wall post is created, other users can share it. If you then find a wall post where someone else shared a post, you can press share to also share the wall post. This only allows you to share the original post, not the new one from the other person who shared it. This generally makes sense, but I think there should be an option to share the entire post by the person who is sharing it. There are lots of reasons why this would be useful. The most common reason would be the chains of repeating an action that commonly show up. For example look at ItzOrangey's latest wall post that shared GalaxyCat24's wall post about rhyming. I wanted to continue this, but I couldn't do so without the hassle of posting a screenshot of it.



Edit: 6/8/2024
I felt the need to point out another common reason for this feature:
When you share a post, you can add text to it. Sometimes you may want to reply to what someone said about it when they shared it.
