Thanks for the quick response, Hannes.

So all we can do is wait?

Surely bendak is right? Maybe esmi thinks you mean something else (left sidebar of something?). And at least in Internet Explorer 11 it is sticky too.

Anyway, I found out by accident that the nav bar doesn’t stick anymore if you make the site-title long enough to overlap the menu-items. So under
Appearance > customize > site-title and tagline > in the site-title field typ a really long text. Uncheck “display site-title and tag line”.

Goodluck

My solution in the comment above led to a new problem: the disappearance of some screen options on the post-page (in the back-end).
I’m going to leave this for now (back to 6 tiles) and maybe get back to it later.

I think i found it. I added this to functions.php in my child-theme:

function twentyfourteen_setup() {
	// Add support for featured content.
	add_theme_support( 'featured-content', array(
		'featured_content_filter' => 'twentyfourteen_get_featured_posts',
		'max_posts' => 100,
	) );
}
add_action( 'after_setup_theme', 'twentyfourteen_setup' );

Then, after publishing a new featured post, I got more tiles.

So to get control over the css for footer widgets, all you have to do is

1. delete the line
wp_enqueue_script( 'jquery-masonry' );
from functions.php or

2. add the lines

function twentythirteen_scripts_styles() {
if ( is_active_sidebar( 'sidebar-1' ) )
wp_dequeue_script('jquery-masonry')}

to your child themes’ functions.php
?

I did the first thing. Not sure whether the second option works.

I just installed the plugin and also couldn’t find the css-file in the Edit Plugins page, but i found the file with my FTP client in
contact form-7 > includes > css > styles.css.
Just copy all the code to your own style.css and then you can edit from the back-end of your site. Good luck.
