We'll create fresh WordPress site with Preserve Editor Scroll Position installed. You have 20 minutes to test the plugin after that site we'll be deleted.
Every time you edit and save a post the page will be reloaded. That means all scroll positions will be resetted.
Not really UX friendly.
This plugin recovers the old scroll position in your Editor after saving. Either HTML or visual editor.
Sounds pretty good? Install now!
If you want, you can drop me a line @ocean90 on Twitter or @Dominik Schilling on Google+.
