Want a toolbar that stays out of the way? Hover to the corner of the page to get your admin links. 
This plugin was made to enable users to get access to the admin area quickly without the default wordpress 
toolbar. The four corners of the page are configurable via drag and drop settings page.
Please let me know if you have any issues with the plugin or you would like to see additions.

This plugin hides the WordPress Toolbar (admin bar) for all visitors and users without the ‘administrator’ role. It’s a very simple plugin with no settings to configure.
<ul>
<li>Use this plugin for sites with only one admin who needs access to the dashboard and the admin bar.</li>
<li>This plugin is super lightweight, with just a few lines of code.</li>
<li>If you need to show the toolbar for other user roles, use the filter <code>habfna_show_admin_bar_roles</code>.</li>
</ul>
This plugin is a tweak of the code by Yoast to hide the admin bar for non-admins only.
