I have seen the need for a pinned or saved post section discussed recently, or for an opportunity to write a small statement that will come up with a resteem.
An opportunity to write why you are resteeming. Sometimes a post really resonates other times I resteem so I can find it later. Maybe these two things should be differentiated. It would be nice to be able to write a line or two when resteeming. Yes that can be done in the comments, but in some posts that can be lost, and the post has to actually be opened to see it. A small statement about the reasons for resteeming should appear in the feed to encourage others to click on it.
