We'll create fresh WordPress site with Toolbar Publish Button installed. You have 20 minutes to test the plugin after that site we'll be deleted.
Too often it turns out very inconvenient to scroll WordPress admin page back and forth in the quest for the big blue button to save latest changes.
Simple jQuery script of this plugin duplicates Update / Publish / Save Changes / Save Draft / Preview Changes button for posts, pages, custom posts, taxonomies, user profiles, and settings to the top WordPress admin bar, so that it stays on site while you are scrolling your admin page. The plugin options allow to keep the scrollbar position after saving.
The plugin is well-integrated with the Advanced Custom Fields, and capable to leave open ACF field groups after saving your edits.
The plugin does not affect any native WordPress functionality, it just redirects your click to the original button, and uses the current button text, of course, with the current language.
