+1 from me on this feature request. (It would be cool to see an awesome theme like this also support microformats v2 as well. Sempress is the only theme out there that does this already see: https://github.com/pfefferle/SemPress, so it would certainly set the theme apart.)

@raumzeit77 As a temporary fix for the IndieAuth piece, you could add a text widget to your site that helps you get compliance with some of the IndieWeb Specs. You can also repeat some of the social icons with "invisible" links so that they don't actually display on the page, but are machine readable for IndieWeb purposes. It's not the best fix/workaround as you'll need to remember that the "invisible" code is there at some later date, but it should get you over the hump. Keep in mind that not all providers work with IndieAuth, though platforms like Twitter and GitHub do.
Try putting the following into a text widget (some portions will be visible others, link tags for example, will not):

<pre><code>
&lt;div class="h-card"&gt;
&lt;link href="https://facebook.com/USERNAME" rel="me"&gt;
&lt;link href="https://twitter.com/USERNAME" rel="me"&gt;
&lt;link href="https://plus.google.com/+USERNAME1/posts" rel="me"&gt;
&lt;link href="https://www.pinterest.com/USERNAME/" rel="me"&gt;
&lt;link href="sms:+12125551212" rel="me"&gt;
&lt;link href="mailto:me@emailaddress.com" rel="me"&gt;
&lt;br/&gt;&lt;br/&gt;
&lt;img rel="me" class="u-photo" src="http://domainname.com/site_icon.png" alt="" width="200" height="200" /&gt;&lt;br/&gt;&lt;br/&gt;
email: &lt;a class="u-email" href="mailto:me@emailaddress.com"&gt;me@emailaddress.com&lt;/a&gt;&lt;br/&gt;
phone:&lt;span class="p-tel"&gt;&lt;a rel="me" href="tel:+12125551212" &gt;+12125551212&lt;/a&gt;&lt;/span&gt;&lt;br/&gt;
&lt;p class="p-note"&gt;
&lt;span class="p-job-title"&gt;President&lt;/span&gt; and &lt;span class="p-role"&gt;CEO&lt;/span&gt; at &lt;a class="p-org" href="http://domainname.com" target="blank" &gt;Company Name&lt;/a&gt;; &lt;br/&gt;
&lt;span class="p-locality"&gt;ANYWHERE, NY &lt;/span&gt;&lt;span class="p-country-name"&gt;United States&lt;/span&gt;&lt;/p&gt;
&lt;/div&gt;
</code></pre>

Some of the code will also qualify you for some additional levels within the IndieWeb identification space relating to h-card.
