If your site is hosted on <a href="https://uberspace.de/" rel="nofollow ugc">uberspace.de</a>, this plugin is for you. 
It adds a menu to the admin bar containing links to the most important pages you might need regularly:
<ul>
<li>Uberspace Dashboard</li>
<li>Documentation Wiki</li>
<li>Email Support – a click opens your email software with your user and server name in the mail body.</li>
<li>Adminer and phpMyAdmin</li>
<li>Webmail</li>
<li>Webalizer</li>
<li>Twitter account</li>
</ul>
The menu is visible for (network) administrators only. 
The plugin requires at least PHP 5.4. You will get an error during 
installation if you are still using an older PHP version. 
<a href="https://wiki.uberspace.de/development:php#php-version_einstellen" rel="nofollow ugc">Update PHP</a> 
in this case.
Please note this plugin is my private project. It is not released or supported by Uberspace. 
Please ask your support questions in 
the <a href="https://wordpress.org/support/plugin/uberbar" rel="ugc">plugin support forum</a> only.
If you don’t have a support question and everything works as expected, consider 
leaving a review. I like positive feedback too. 🙂
