Plugin Floating Publish Button

Floating Publish Button is perfect especially for editors who use the page and post editing interfaces more than regular administrators.

They’ll find this plugin extremely useful, since there won’t be any need to scroll up and hit Publish/Save every time they want to update the post, especially if it’s a really long post or a page with lots of metaboxes.

If this behavior is annoying for some users, it can easily be turned off from the user’s backend profile page.
