Pin in DM Channel

If you look at other messengers, there is a function that keeps the DM channel pined at the top. I'm writing on the feedback board because it's a little disappointing that there's no DM channel pinning function in discord with message pined function.
First of all, it would be nice to have a function to place a pined channel under that channel when there is a newly pined channel, and to place the newly pined channel at the top. Alternatively, if pined channels can freely manage channels with drag-and-drop functions, DM channel management will be much easier. I want this function so much that I write this article.
