SMF 2.1. The height of the post editor matches the size of the text.

[User2]

Hello.
I am informing you of my wish. I would like that when a forum user enters to edit a post, the height of the editor corresponds to the amount of text in the post so that the user sees the entire post.
Now the user needs to manually increase the height of the editor to see the entire text of the post.

[Kindred]

OOf.....   as a long time internet user (and by that I mean I have used the internet since before it existed as such) I;'ll tell you -- that is a TERRIBLE idea.   It's horrible UI/UX.
