Editor scrolling on save in WordPress
WordPress has a good editor, in my opinion, this editor has obvious inconveniences.
Every time, when you save a message, editor scroll position will be on top again. If you want to keep writing a long post, it will take you a lot of time, until you find the old cursor position.
To avoid this, I found a code snippet on the Internet, which I want to share with you.

At the end, as always, some delicious. I suggest a plugin with a similar action Preserve Editor Scroll Position.
